Prius (Gen 3) :: Rear End Don't Rebound On Speed Bumps
Sep 22, 2012
In the last few thousand miles, I have noticed that the ride in the rear of the car is rather rough compared to new. For instance, you can feel the roughness and choppiness from the driver seat. When going over speed bumps, the rear end also does not seem to rebound nearly as well as the front. The front struts though, are working just fine.
At first I tried rotating and balancing the tires; the improvement was minimal. At the time I had springs from TRD on the car, so I reinstalled the original Toyota springs from the factory. The rough, choppy ride from the rear now became less noticeable, but is still there. I currently have 43,000 miles.

I'm new to vw and I have a passat 3.6 sel premium and I have been hearing a noise coming from my rear suspension when I have a full car or going over speed bumps and such. It took it to the dealer and they said that they couldn't replicate the problem, could it be the control arms or it's bushings? The car is only 6 months old smh.

So on the 16th I had my Koni FSD kit installed with a set of Driver Gear springs (30mm drop) and used the ECS Tuning install kit for both front and rear.
The issue I'm trying to troubleshoot is a 'thunk' noise coming from the rear but only when going over speed bumps or any other major bumps/dips.

I'm in the market for an '09 Sonata 4cyl. I found a good looking one at a local Toyota dealership (supposed trade in). Unfortunately, the dealer claims there are no service records available...test drove it and heard noise coming from rear suspension when going over speed bumps. Dealer had tech look into it and said they lubed up the 'springs' and stabilizer/sway bar and now the noise is gone. Should I run away or take this thing in for an independent inspection, and if it checks out, buy it without the service records?

I recently bought a CPO 2007 GX 470 with 110k miles. At no charge dealer made repairs re the Bulletin about clunk in rear when I slowly drive over speed bumps. Had all front and rear shocks raced with OEM shocks, and four new Michellin MS2 tires installed. Rear end still feels like is is bottoming out sometimes during regular local and freeway driving when going over different times of road bumps.
My 'i89 a Dodge Ramdharger ( only car I ever bought brand new off the lot ) with 174k miles and old shocks and original springs drives better over bumps and speed bumps than the GX. One Lexus dealer said the reason is because the rear air bags ( that are not leaking )do not fill up fast enough when going move bumps and that can cause the bottoming out feeling. My mechanic is going to check it over again. What could be causing the bottoming out feeling?

I bought an 02 Explorer Sport 2wd back in December of '12. The vehicle actually runs pretty well. The thing I first noticed was the rear suspension seems to slam when going over bumps of almost any size or at any speed. Like if there's a sub-level manhole or something that just the passenger rear tire goes over it makes this terrible slam and sometimes shimmies (Spell check) to the sides like Inam losing control. I thought I would go ahead and change the shocks, did not make one bit of difference. I have looked up diagrams on the rear sus and everything seems to be there. Here's a picture just to kind of show what I have going on.

I have a 2004 F150 4x4 5.4. Over the last few weeks I've noticed that when the truck has been parked for even a short time, when I start to move out I am getting a thumping noise from the rear, almost sounds and feels as though I am driving over small speed bumps, but once i get going it seems fine. Where to start?

My dad recently backed into my front right side. There was very little exterior damage but it still had a dent. I took out the dent and checked under for any visible damage and didn't see any. Over the past 3 months something has developed a little worse. It started as a small little crunch on the right side when going over speed bumps. Now on turning left hard or stuff like that and I hear it crunch. Its worse with more weight. It sounded like plastic but there's no loose plastic or anything. It's 05 Prius with 150k and I don't think there were any replaced shocks done. I bought it used.

I had the front struts replaced. I looked at the strut diagram and replaced most of the parts associated with the front struts. The rear shocks were also replaced. New brakes were installed on the front and rear. The front rotors were replaced. Mileage 124000 miles.
I thought this would might solve the squeaking when I went over a speed bump in the parking lot. It did not. How to fix the squeaking.

Saturday, I parked the car and tried to lock the doors with the fob. The car held a constant beep but would not lock the doors. They locked fine from the driver's door.
Later as I was going over a speed bump, the car bleeped, the cabin light came on and off, and the display showed 'key found' in a period of 10 seconds. This speed bump anomaly happened twice later that day. Dark, I want to wait until dawn before getting serious into the debug.
My first thought is a loose ground wire or 12V connector. The last work was the brake accumulator recall. If the technician did not torque down the ground connector, there would be high resistance leading to the key fob lock problem as well as the speed bump triggered reset.
I also have a miniVCI so before doing any work, I'll use it to look for error codes. There are more than one connector that could be loose and having the codes could give us a clue if it happens again.

Every time I go over a speed bump, I hear a very noticeable grinding noise as the tire goes up it sounds grindy and as it goes down it sounds grindy front driver side area. Took it to a dealer and they said there is no problem. Therefore, should I just forget about it until there is a problem? It doesn't affect function, but I do hear it going over speed bumps and not regular shallow bumps.

I just got back from Town and Country Toyota charlotte, NC. They did my oil change and tire rotation. I also told them the rear spoiler is loose and making noise over bumps, they ordered a new one under warranty. I also wanted a new driver side wiper blade, they also are ordering a new one under warranty. So so far they are doing a good job. I have been there one time before.

I almost bought a Gen 2 Prius, right before the introduction of the Gen 3. Then I waited a few years before I finally bought my Gen 3 Prius.
Don't let this out. But it's bothering me that I'm no longer at the top of the Standard Prius evolutionary chain.
The Gen 4 tribe is chipping rocks to make arrow heads... and using fire to cook meat and provide warmth...
Every time I go over a bump, the term Independent Rear Suspension pops in my head. An instrument panel that has multiple colors. I can only grunt and slobber and take what comfort I can from the pale light of the vacuum tube like glow of the Gen 3 instrument panel.

Some days in the mornings there is a squalling sound that comes from the rear of the car. It only last for a few minuets and only happens at low speed under 20 mph. Once it stops it dose not come back until the car has set for a long wile like 8+ hours or over night.

Clunk in the front end when going over speed bumps? That is the only time I ever get it, never on bumpy roads or anything like that just at speed bumps. It seems to be louder on the drivers side but I am pretty sure its on both sides. I never noticed it until a couple speed bumps were installed along my normal route, but that could be because maybe I never drove over them previously?

My wife has a 2006 GLS and the top strut mounts need replacing, they squeak during the winter when i go over speed bumps. Since i drive the vehicle more than her (i have a 92 accord that i drive to work daily lol) and i have to modify every car that i own. Since i will be taking the strut assembly apart to change out the mounts it gave me a good reason to purchase lowering springs ( coilovers are not in my budget).

I have a 2000 Nissan Xterra with about 100,000 miles. When I start out and get between 45 and 55 miles an hour, it sounds like I am going over speed bumps in the rear end. I noticed that it seems to come on more when I let up on the gas and barely gas it again. What the problem could be?

Once in awhile, as in maybe once a month or every few thousand miles, I hear a rattling noise in the rear below the car. It is very audible and everyone in the car notice it.
This happen only when I have been in traffic for awhile during which:
1) when battery is running really low from moving at low speed
2) After which the engine is turned on to charge the battery
3) moving low speed with the engine running.
The vibrating noise increases as my speed increase, getting more audible and vibrating faster. After a certain point (maybe 30 mph) the noise stopped.

I Spent the day yesterday replacing all four struts on my '07 LE. I went with KYB, the installation went well (so I assumed). I put everything back together exactly as I took it down. Outside of the struts alone, I reused all other parts as everything seemed to be in good order.
Test drive: I seem to have a knock/clunk when going over bumps/pot holes at low speed (<35 and especially <15mph). At highway speeds (65+), I do not hear it at all, even if I hit something. I had a friend ride in the back and confirm that it was coming from the driver's side (left) rear.
Took everything back out and inspected, I noticed that the strut mount has a flange that runs to the flat side of the strut rod that looked a little worn, so decided to go buy a new strut mount (Monroe garbage, only thing available locally). I did notice the Monroe strut mount didn't have that flange the OEM one had, it is just a circle...I didn't know if that mattered. I Put in new strut mount on, same sounds in the same conditions. I want the clunk to go away.
