I think I may have figured out the reason for all the noise in the rear... I have tried isolating every bit of the rear coilover to find where the noise is coming from. (squeaking, thuds) After many attempts with no solution and even two different coilover systems (buddy club and Stance). I believe the problem to not be with the coilover unit at all.

Instead the problem is with the lower mount of the rear shock. Which is a weak rubber bushing. This bushing was originally intended to only withstand the dampening force of the factory shock absorber where most of the weight is resting on the spring in the OEM location.

But with a true coilover in the rear you are now putting all the weight of the rear plus all the force of shock on this single bushing. I looked at it closer this morning and mine is starting to crack and is no longer doing its job. I believe this is what is making the noise.

Please everyone with true coilover in the rear check and see if yours is wearing pre-maturely. If this is the case, we need to fabricate some spherical bushings for this location.

 

good find

 

checking

 

Ohhh...good find bro. I'll look into that one with my shop.

 

I may have something to reduce inpact harshness related to the springs. Your rear springs use 2.5" inside diamter springs, right?

I made isolation rings out of a silicone rubber material, greatly helped with my impact harshness issues with pillowball upper mounts. It's the white material you see in the pic below.

 

still havent checked, but ive never worried because they never sounded more squeaky then my previous coilovers.
I have alot of problem with lifting one wheel in the air when going up slopes at an angle like parking lots because my rear shocks dont have much travel.
does it happen to anyone else or is it just the consequences of how ive setup my suspension?

 

My rear suspension lifts a wheel coming in at angles all the time.

Any one know of any shops that could make some spherical bushings?

 

^ maybe you could ask Alex @ Battle Version.... i'm sure if he knows it is an issue, he would have some made, ... I think getting a polyurethane bushing in there might be better for daily driving...

Or try SPL or possibly SPC. SPL is already making the aluminum rear diff bushings...

 

yeah, ive mines cracked ill be calling him immediately

 

I emailed SPL parts and Alex at Battleversion. We'll see what they respond with.

 

^ Nice! Keep us posted.

BTW...when you guys go over driveways, do you guys get popping noises from the rear? It varies per driveway but I get several popping noises from the rear when I go up or down a driveway. I don't think it's clunking like what some people have called it but I could be wrong. I get nervous since it sounds like my suspension is going to break off or something. Not sure if it's the coilovers or the fact that I have my sways set at full hard.

 

Where did you find the silicone material?

 

Is it a creaking/popping sound? You have coilovers? If so, that's probably your springs compressing/turning when at funky angles...
or it may be your sway bar too, ... but that really wouldn't make that much noise...

 

Is there an aftermarket bushing available for this?

 

Even though SPL says the spindle isnt very substantial, Spherical/metal bushings will help with the noise and integrity of the suspension.

 

just the sound of my tire hitting the floor, and Ive ahd a tick tick tick from my axle when my car was stock, but so have alot of people.

i wonder if the one wheeling has caused yours to crack from coming down, is it on both sides?

 

Well...it's not the axle clicking noise since I know how that sounds like. It's only in the rears & yes I do have full coilovers (Stance). It's pretty loud & annoying so I'm pretty sure it's not normal. Hmm? I'll probably bring it in to the shop to have them take a look at it this week.

 

Anyone else interested? I'll start looking into materials to make this part.

 

An unlikely source. Home Depot, faucet isle, search the misc repair parts section and you'll find this.




Mark the size you need, start a cut with a razor, finish with scissors. I'm using 2 stacked at the top and one on the bottom.

{edit} my picture hosting site is having some trouble for some reason

 

i think SPL is dead on with their view, ... i think the aluminum bushing Will help, ... but i'd worry how it will affect the upright, ... i mean b/c of the small size of the upright, i could see an aluminum bushing weakening or cracking that 'housing'. That's the reason i was weary of going with true coilovers...

I'm sure there will be a full spindle/upright replacement within the next year...

But for people who need something now, ... I would think you could get a properly sized urethane bushing (which I think would put less stress on the upright) from prothane or senergy suspension ....they list quite a few sizes for their shock mounts/etc on their website(s)... you can probably also get a urethane spring isolator to help with the noise...

just a thought...
