Slow speeds. I am noticing a roaring noise. Almost like a big truck with oversize tires. It doesn't seem to change turning left or right. I rolled each wheel and didnt get any play. Rotors and pads in great shape. I did notice when one wheel is jacked up and I turn it (clockwise/CCW) it seems like there is a lot of play...maybe in the tranny or just the axle.
View 1 RepliesWhile on a recent 800 mile trip, by the end of it (on interstate driving) a roaring noise was coming from the from tires. A quick inspection showed nothing amiss. It's a 2001 Volvo XC70 with 108,000 miles. The Michelin tires were new at 100k. No shimmering or shaking at higher/lower speeds or changing lanes. Just the annoying new roar as the car gets going over 20mph.
View 7 RepliesFour months after I bought my Prius III last year, we discovered that the left rear wheel was so out of alignment that it ruined the tire in 5,000 miles, and then also ruined the one put in its place during regular tire rotation. Toyota replaced the entire set of tires, and I checked the alignment this fall and again this spring when I took off the snow tires.
Everything looked fine. Nevertheless, when I rotated the tires today, the tech reported that ALL FOUR tires were substantially cupped on the inside, after only 6,000 miles on this set of tires. Road noise has become much higher. It doesn't make sense that all four wheels got similarly out of alignment in just two months.
2010 F150 XLT 4.6V .... Not too long ago my truck started making this whining/roaring noise when I accelerate. It does not matter what speed I am going from the slowest to the fastest it makes this noise but it does not make it when it is idle or at least it is not loud to the point where I can hear it while inside my truck. I am not sure what this can be I am at about 51,000 miles and have no problems other than the noise besides the fact that to me it seems as if it pulls at times when I drive it but others say they don't feel it pull. So I am not sure what is going on and I do not want to take it to any mechanic I'd rather fix it myself and know what is going on with my vehicle?
View 5 RepliesI have a 97 F150, 2wd, 4.6, auto bought for a great price agout 3 months ago.... I installed a cold air intake (air raid) and a throttle body spacer with the swirling cuts.
Since the cold air intake add, the truck occasionally makes a load "roaring" sound from the intake system. At same time rpms increase 500-1000 rpms...
it doesn't do it all the time, mostly at low throttle, and a quick jab on the accelerator usually stops it. sometimes such as when parking, holding the brake and applying a bit of throttle with load from the brake will also stop it.
Guys at local garage seem to think it has something to do with lower outside temps, (denser) and addition of cold air intake. it made the noise before the throttle body spacer.
At what pressure the TPMS light is activated? I noticed my daughters tires were low and when I checked they were at 15 PSI and no warning. Its a 2010 MY Prius III .
View 7 RepliesI was pulling out from a side road onto a much busier road. I had a small gap, put it in pwr mode, and hit the accelerator. Much to my surprise I actually chirped the tires. I only use eco mode, so I am not used to how quickly it gets into the ICE when in pwr mode. Consider me impressed with how this car can actually do it all
View 2 RepliesI have a 2011 Prius. I put 15" aftermarket summer wheels on it and a vibration appeared The wheels and tires have been rebalanced many times. Wheel alignment has been done, wheels replaced, tires replaced but the vibration is still there. I am now back to the OEM and the vibration is still there.
View 12 RepliesSo I bought a used 2010 Gen 3 with ~26,000 miles on it in July 2013. I started out getting 48-52mpg depending on where I was driving. I live in Raleigh, NC and I did notice a drop in drop in MPG over the winter ranging between 44-48mpg but the mpg never rose again as the months warmed and I averaged 44-46mpg for most of the summer. After changing my tires a few weeks ago I've dropped to about 40mpg regardless of where or how I drive. I bought Pirelli P4 Four Seasons 195 65R15 91T and have them inflated to the levels recommended by Toyota. 35/32 or something like that. Is it the tires or is there some other possible issue?
View 19 RepliesMy Bridgestone Ecopias(Ep20s) have 26,000 miles on them and are wore on the outer edges. Both sides are worn. I heard this may be to under inflation. I go to Discount Tire and they set all my tires at 37psi. Is this too low. The door says 35 front and 33 rear. Do I need more air for them to wear evenly? Also I have ordered Michelin Energy Savers. Discount will set them at 37, or should I add more air so this type of wear does not happen? I plan on getting an alignment just in case, but really don't think I need one. There is no pull to either side and the wheel is straight.
View 19 RepliesWhen I had this set of tires rotated and balanced for the first time I picked up a vibration. I can feel it through the steering wheel and the floor, it starts about 40 or 45 mph. It is not severe but it is annoying. The tires are Michelin Pilot Sport A/S Plus size 215/45-17, they had about 9K miles on them when I had them rotated. Before they were rotated they were as smooth as glass.
View 18 RepliesI got two new Bridgestone ER300 Ecopia to replace two on the front. Trouble is after getting the tires fitted the car pulled to the left quite badly and my mpg's went down! Hmmm. I checked the tires in case a non low rolling resistance tire had been fitted by mistake, but they were correct. I then checked the pressures, which again were correct. So I guessed the tracking must have been out so booked it in with the dealers for checking. After a couple hours and a couple test drives later they advised the tracking is fine and the tires are fine. Odd.
Just filled up for the second time since the new tires and I'm struggling to get anywhere near 50 mpg! Even after a few long trips where I know from past experience that I could get mid 60's easily. I've inspected the tires closely and note that one of the new ones is made in Italy and the rest are from France. All the loadings, ratings and the type are the same, just made in a different factory and it is a slightly lighter colour compared to the French ones.
Last October I needed new tires, so I had Michelin Defenders put on my 2011 Three in place of the OEM Firestones. The Michelins perform well and are nice and quiet, but...
My gas mileage (both indicated on the dash and calculated) has dropped by about ten percent. In researching the two brands of tire, I found that the OEM Firestones are rated at 836 revolutions per mile, and the Michelins are 839. I'm wondering if this is the reason for the apparent change in mileage.
The car was purchased used with 18" wheels already on. After driving for about 6 months, I started noticing the road noise getting very loud. I took the car to a tire shop and they told me that there was some uneven cupping in the middle of the wheels, which is usually caused by worn out shocks making the wheel bounce up and down.
I replaced all 4 shocks, then replaced all 4 tires. Now its much more smooth than before, and is very silent on nicely paved roads. however, I notice when there's roads which any imperfections (like fixed streets with tar.. or uneven pavements, or when your tire hits the freeway markers to keep you in the lane) its heard very loud from inside the car and creates an almost *thud* sound when it does.
I assumed that the problem was that the car had 18" wheels. So recently I swapped the wheels out with stock 15" from Toyota, but somehow the road noise is still very apparent. I sat in a friend's Prius, same year, and I could tell that it was handling the uneven pavements much softer.
What could be the problem now? Is there anything else that needs to be replaced?
The steering wheel mysteriously clocked itself slightly to the right after changing out the standard tires to same sized studded tires for winter. This has never happened before and I was unaware of any alignment/wheel clocking problems up to driving into the shop to swap out the tires on the wheels.
Air pressures were all good and even all around--but I don't know if they were even before the change-out. Also, the wheels were balanced and the drive afterwards revealed no pulling either way or vibrations. On top of that neither the tire store nor my Toyota dealer had any explanation(s).
I'm only guessing at this point that prior to studded tires there might have been a clocking error so slight it was not perceptible in over 5K miles and with the studded tires now it is perceptible.
Q: Is it possible under my circumstances for a different set of tires on the same wheels to make this sort of difference?
I tried to reset my TPMS light using the procedure in the owner's manual after installing my snow tires on the OEM wheels. Now it looks like there is no effects as the lights will just keep blinking even if i am holding the button down. Does this mean the tire shop broke one of my sensor during the install?
View 5 RepliesI just drove my Prius through 8-10 inches of heavy wet snow. The car did amazingly well. At times my traction control light was on when trying to get up an incline until the car got going. Then when I got home I stopped in my driveway for the garage door to open and started into the garage. The car was stuck, but then the light came on and the car climbed the driveway in about 10-15 seconds and made it in the garage. I then noticed a smell like burning tires. Maybe it was the tires from spinning. I hope that I didn't hurt my transmission or another component. Does the Prius protect itself if it is stuck and the traction control light is on from overheating something? I think I recall that the 2nd generation Prius would not allow for wheel spin to protect the traction battery.
View 5 RepliesI hear a roaring noise coming from the front of my 2003 Jetta. I know it needs some kind of front end work, but I am not sure what. The front passenger side tire also wore badly and prematurely on the inside and outside.
View 8 RepliesJust recently starting hearing a loud roaring noise while driving my 07 Camry V6 XLE. It sounds like the gears are not shifting, like it is staying in low gear. Sometimes the sound will lessen if I'm driving over 15 mins. and some times it doesn't. RPM is around 2 or less, typically 1.5. Tried to check the transmission fluid but could find the stick. The car has about 142,000 miles. I hope the engine is not going.
View 1 RepliesWhat could be causing a loud roaring noise when accelerating. I'm thinking it may be in the transmission but not for sure.1st I thought it was a CV joint going bad. Also acts like it's in 2nd gear. 2006 Malibu Maxx SS , 97,000 miles....
View 6 Replies2008 Toyota Prius about 45K miles, just did 3Kx2 Cross Country, and now I notice a "roaring" constant sound from about 35 - 50 mph. Seems to subside at higher speeds, although this may just be that the sound is being drowned out by freeway noise (and radio!). Mileage has remained consistent, and no performance issues observed. Maintenance is current. What this could be?
