Clunking noise help

I have had problems with my passenger seat rattling, I know others have already pointed that out but have you tried reclining it and then forcing it all way back so it is pressed firmly against the rear seat. This should remove any free play have and maybe solve the sound.

Let me know if your noise goes away once you pull the fuse. I'm curious if cutting power would actually stop the rattle.

But I'll give the passenger seat a try too. Thanks for all the great suggestions everyone!

I know we're just pissing into the wind but that clip sounds suspiciously like either of the issues I suggested.

Can the EPS chatter be confirmed simply by turning the wheel ever so slightly while the rattle is happening? I've never experienced it in person.

I am with you on this. Most of the other issues mentioned here create a snap crackle or pop. That is a good solid clunk and I do not believe it is any of the "normal" sounds.
I am 95% sure that this has been mentioned by other early PP buyers and it was something to do with the springs but can not find the threads where it was discussed.

Look for the simplest solution first.

I had a similar clunking sound from my front end. Only heard it at low speeds, on turns and over bumps.


The tire shop couldn’t locate the problem, said it was solid and told me to take it to the dealer. The stupid dealer told me it was struts. I changed those out with some used ones from eBay. Didn’t fix it. Ended up changing the ties rod end and sway bar link on the right side and that didn’t fix it. All the parts looked good when I tested them but I changed anyways since I already had them off. Then one day I just got determined to locate it so I got underneath the car and pull and pushed on everything. Ended up noticing the front grill was pushed in from parking the car over one of those wheel stops and having the rebar pull the front end a little and popping the grill in. Popped it back in and am relieved to have finally found and fixed the clunk.

I'll try to get under the car in a few days and check out your suggestions. The snow will be coming down pretty good the rest of the week so I'm going to be staying warm inside.

Just figured I could try the EPS fuse real quick at work.

Noise is present going over bumps at low speeds (under 50) and seems to go away at highway speeds. It's definitely coming from the rear, more so the passenger side but sometimes the driver's side as well. It's sounds like something is loose and clunking around.

I have the same thing on my '19 86 w/ trd suspension @ 6k miles. It seems to only happen at low speed on big lumps in the road. There are a couple right outside my house that always cause it. The road has these kind of dips that cause the car to go up and down a lot, where at higher speed I think the shocks absorb the bumps and keep the car more level. Sounds like something might just be loose in the trunk, but I don't see anything that is. Haven't given it much concern though. If I find out what it is I'll let you know.

The fuse had zero impact on the EPS chatter on my car so that method of ruling EPS out is a fail. Wow is it had to steer without PS. 13:1 ratio is no joke. Even when moving it’s nuts.

My car does have a thump when turning the wheel left/right with the car parked and turned off. Thump isn’t a good description though. It’s a lighter and higher frequency sound. Crank it probably a better word.

I will grab some audio recording of what mine sounds like when turning the wheel while parked and what I hear on road reflectors and under braking.

Edit: oh you are talking about while moving. I will give that a shot next time I’m out.

Yeah, I figured loading it up to one side or the other would do it.

Well then I won't rule that out for me either.

If I put my head over the dash I don't hear my noise coming from up front. If I stretch my head over the back of my seat I definitely hear it louder coming from the rear. The sound could be resonating around and a passenger would sure help locate it. But for now I'll focus on the rear end and keep this in mind if that gets me nowhere.

On mine you can put your head down by the pedals and yank the wheel left and right and clearly hear it coming from the EPS unit. If you do that test and don't hear it coming from the EPS unit then I'd say that isn't it.

I did some testing this morning and under hard braking it goes nuts but if you turn the wheel slightly while braking the sound stops.

Makes perfect sense.


And for the PS unit to develop such a rattle really is disappointing.

[ls1ac]

Early on you said the sound changed when you put the seat down. Did you take everything out of the back and the seat down? With the back open to the metal you can hear the back suspension at work.




There was something early on but like tcoat my memory fails, what were we talking about?
