Experienced a rear axle whine above 70mph? I've noticed a whine while just slightly on the gas above 70mph (maintaining speed). Does the GX have a regular ring and pinion set up or is it a more complicated affair?
View 14 Replieshad a leaking rear driveshaft seal at the axle and replaced it and fluid. 75W145 full synthetic as recommended. it was changed at 128000 and I've started to get an axle whine over 25 MPH up to 65-70MPH. quites down around 80 MPH. I just checked it after 2 months (whine just started) with 133000. Any TSB. does this fall under TSB 05-23-3? Noise sounds like I've got really aggressive tires on the truck. Only have Dayton HT all season. Did not add the XL3 additive. Would this work at this juncture.
View 5 RepliesWhen I am coasting in reverse or forward at low speed e.g. 5 mph, I am hearing a whine that seems to be coming from the rear axle.
Usually it happens just after I have shifted OUT of gear (it's a manual transmission).
I uploaded the sound as a WAV file to here: Note! I recommend that you disable flash before going to this [URL]......
When I speed up the whine just rises in pitch and it's making my ears ring. What that sound might be? Maybe I just need some "axle grease" or something?
I had the rear axle seals replaced less than 1000 miles ago. Now the axle is getting whiny. First I thought maybe that the tires made noise but now I'm pretty convinced it comes from the axle.
With a seal replacement, what do they do that might impact the axle - over tighten the bearings?
I also had the rear diff fluid replaced - perhaps they put in the wrong stuff...
Should I replace fluid and see if that stops or should I simply take it to the dealer and let them deal with it?
I have a constant whine going down the road with foot on the gas. Back off and it quiets up. At 2-3 MPH i think i can here a " tick- tick". Took the drive shaft off, wheels off ground, cover off and oil out. Spin wheel and i can hear a tick - tick, I think around the pinion bearing. No play up and down or in and out, but it appears to have 2-3 times the backlash i would expect. I used the screw driver- stethoscope--- still think its the bearing. This is a 9.75 axle. What kind of luck would I have pulling the yoke off and going in from the front without removing axles halves and ring gear? I thought I had read that here before. Never done one that way .
View 2 RepliesSo today I took the gx470 on the highway and once is approached 70mph i noticed the steering wheel shaking... never before have i noticed this but today it happened i guess sporadically... just the steering wheel and nothing else... is this just the alignment? bad road? excessive speed? funky... lmk
View 8 RepliesI recently had my rear axle seals replaced due to leaking. Does the rear diff fluid get replaced on that repair since the rear diff cover comes off? Trying to figure out when my next interval for changing rear diff fluid should be.
View 1 RepliesCar was in the garage. Had been off for hours. Husband noticed a high pitched whine coming from the rear of the car. Louder underneath. I opened the trunk and took out everything in the cargo net (thought something had gotten stuck in it, a gadget of some kind). Nothing there. I went to unhook the net and pull up the mat etc. and the noise stopped (coincidence I'm sure). I couldn't find anything. It didn't sound like it was coming from the wing at all (had trouble with wing being stuck down when I first got it).
View 13 RepliesIve seen this also on some 4runners. Ive had several vehicles many years old with no rust underneath at all and I check today and sure enough, some rust on the rear axle and in front suspension arms. I checked the lexus warranty and it is unclear whether this is covered.
View 14 RepliesI got a new to me truck. It's a 2004 F150 Lariat 4x4 with the 5.4L. It's got a whine that I believe is coming from the rear differential. I'm going to change the fluid. My axle code is 26 which I believe is 3.73 non-limited slip. My owners manual says to use 75w-90 but I've seen a lot of posts on here that say to use 75w-140. Which is right or better? Also, is my rear differential the 9.75"?
View 14 RepliesMy '04 4wd has a pretty loud rear end howl, it is a LS but don't think it's an LS problem, no noises or chattering when turning. Howling is loudest at 50 to 60, but some noise at all speeds. I don't mind tearing into the rear myself, but not sure if I could tell what was wrong just by looking, i suppose bad bearing might be obvious, but not sure how to diagnose gear lash tolerances. It only has 107000 mi. and is an 8.8 rear I believe.
View 2 RepliesI've own my Lexus sc430 for a couple of years now and I've been experiencing some problems. Its a 2002 sc430 with 77k miles. When I drive on the freeway at around 60-70mph the car decelerates. Everything else is working. The car feels like I let off the pedal, but I really didn't. I went to the my mechanic and try to see if any codes came up but nothing. Also hooked it up to the scanner while driving and when the problem happens still no codes. the mechanic cleaned the MAF sensor and throttle body. He said he thinks it might be fuel filter problem. I read that the Throttle Position Sensor could be the problem, but when I told my mechanic he said he doesn't think that it could be the problem or else it would throw a code. The mechanic also thought that it could be that the tires are low on air so he filled them up and drove home and had no problems. but I feel its still might happen. a
View 14 RepliesI have just become a proud owner of a gs450h 2006. So far i love it. Just one thing i wanna clear up for peace of mind. It is a cvt gearbox and when i floor it there is a brief pause in power at 70mph ish. Then it flies full power the kw gauge goes all way but a lot faster than the acceleration previous to the flat spot. Its like it changes gear at 70 and hits a massive powerband but id like that to be instant and sooner.
Hybrid passed all tests last week at lexus.
I had a loud whine from the rear axle of my 04 SCREW and had the bearings replaced at the dealership. It has been about a year/12k miles since it was done and I just noticed that the vent hose is missing. I'm not sure if they left it off or if it fell off on its own. Anyway, my question is, do I need to replace the fluid once I put a new hose on? I'm not sure how much if any dirt or water might have gotten in there. Also, where does the hose go up to? I figure it must clip to the frame somewhere.
View 5 RepliesIt seems that every time I put the truck into 4 low, the rear axle locks up. When turning, one tire skips no difference which way I turn. When doing this, I do not have the front hubs locked. Also noticed that when turning in 2wd one tire will spin w/o other locking up. I have spun the tire enough for the L/S to catch, but hasn't. I have heard that the locker was not available until years later. Is this true?
View 11 RepliesI own a 2004 F-150 FX4 5.7L V8, I notice this morning that I had gear oil coming out of my rear Axle Vent Tube. What would cause this issue? I'm kinda at a loss as to what would cause it.

View 9 Replies2004 Ranger Edge 2wd 3.0L. When the truck has been sitting for a while and i start moving forward there is a very loud sound of metal on metal. Changed the diff fluid last week, used royal purple 75-140 with the friction additive. No change, tried to take rear wheels off, but the drums are stuck by the pads. I was able to get the drums off only bout an inch.
Recently, I've noticed that on hard acceleration the RPM go up but it seems sluggish on acceleration. There is also a vibration that comes from the rear and goes away when i remove my foot from the accelerator. The squeal happens between 15 and 20 mph, but goes away fairly quickly. The vibration happens around 40 or so. I am thinking rear axle bearings? But i cant get my drums off to replace the bearings.
Some family members borrowed my truck, and when they returned I have a loud whining noise coming from the rear axle, which I have determined is a 9.75 rear. I checked oil level and it was high enough, but has a slight leak from the pinion seal. Everything feels solid but I have nothing to compare it to.
Its on a 2005 Super Cab with the 5.4L 183,000 miles. The front pinion seal was replaced in Feb 2 years ago, by the dealer's mechanic, who may have been a shade tree mechanic.
I am a Youtube Certified Mechanic, as in, I watched about 10 videos of people working on their 9.75 differentials, and realize I don't have all of the tools to do the job, such as a press, or race drivers, or the special gauge.
How many of you have tackled this issue? What did you find? What am I looking at for cost? I am on a very small budget.
Just hit 225k with my 2004 Prius about a week ago. I passed inspection without replacing the (slightly) cracked rubber bushings for now, but what worries me is the cracks and a slight hole (it has not rusted completely through). Pictures attached. Should I do anything about this, and if so what?
Also, I've noticed that when I let go of the brake pedal, especially after a medium to the hard stop, I hear a squeaking... what's the cause for that? I know the front rotors have a bit of rust on the edges, but not sure if that's the cause... it seems to come from the back.
Other than that, the only other noise I've noticed is a slight clacking/tapping when the A/C is on, usually in hotter weather. The only thing I needed to pass inspection was to replace the muffler after a year and 1/2 ago, the last non-OEM part they put in at another shop was junk and rusted through pretty badly leaving a hole that was leaking. Ended up getting it replaced at the dealer with the OEM part this time...
I own a 2007 GX470. It has suddenly developed a loud whine. We replaced the power steering fluid (which we were told was filthy) but the whine is still there. The mechanic has suggested we drive it for about 500 miles to see if the noise disappears. I'm not crazy about driving it with the loud noise but don't mind. He says the car is safe to drive.
