Stiffer Rear Mounts/Clunking in Rear???? Solution!

DouglasSXT · Post by **DouglasSXT** » Sat May 31, 2008 2:02 pm

Ughhh. I should have done this when I put my new struts in. I had this issue with my old ones and it pissed me off soo much until I changed them... I did however buy all new hardware, front and rear for the struts... Hope they last, but at least I know a good fix now.

i just used a $5 tube of PL Roof & Flashing Sealant (polyurethane) from Lowe's to achieve the same result... just another way to go for anyone who cares.

First off, Sorry to bring back an old thread.

I Tried this a few days ago (on 66k mi Strut mounts), But wasn't able to let it cure for more than a half hour before i had to throw them back on my car and take off...I'm still clunking

.

I ordered new Strut mounts (Moog) from Advance yesterday, and bought some more window-weld ($18!). This time I'll let them cure for 24+ hours and see how they hold up then

Are SRT4 and base Neon strut mounts the same??

I might do this instead of buying new mounts.. the clunking is super duper fucking annoying..

Ya same mounts.

Got lucky and got the last tube of windo weld. Got my mounts yesterday. Next weekend I will be doing the job

Filled the mounts last Saturday and gave them plenty of time to cure( 3 days). I didn't have time to install all 4 mounts so I just did the rear and let me say this by far is the best quick fix solution for the clunking. Ive been driving around with that noise for so long it actually seems weird that i don't hear it any more..

Thanx SlvrACR for this quick How To..

Measy, and anyone else who did this, did you fill both the top and bottom or does it still work filling just one or the other?

Thanks.

How long did u let yours dry for?

For anyone that cares I'm halfway done with this mod/fix.

I went out and got new mounts, and a thing of Loctite PL Roof & Flashing Sealant ( http://www.loctiteproducts.com/p/pl_sea ... ealant.htm )

To get the strut apart I used this how to: viewtopic.php?t=10341

So far everything is sitting waiting for the goop to dry. I can't wait to see if this finally solves the clunking noise.

update: ahh peace and quite for the back end.

Wait.. so when you use aftermarket struts and springs.. the neons have a clunking sound? Is this due to loose struts or oversized strut mounts? I've never heard of clunking on the struts other than when the nut(s) become loose thus you have loose struts, which clunk on turns/curves/braking/speeding/hitting bumps on the road etc.. happens. <_<;

Does anyone know if this is the aftermarket strut being the problem with the stock mount or is it the springs (assuming lowering springs)?

I'm about to get into a set of struts and springs but it appears I may need additional hardware (after market strut mounts)?

OEM or aftermarket rear mounts, the part that bolts to the body. The inside rubber becomes loose.

trojmn wrote:my fix because didn't like the thought of the top of the strut moving about even on a "good" mount... and i don't see any need for spherical bearing mounts in the rear

also a great visual to how ridiculous strut bars are unless you fix the strut mount....

Duster360 fabbed a permanent fix and firmed up the rear strut mounts quite a bit with 3" diameter neoprene. Drilled the spot welds on the old mounts, and took out the destroyed guts. cut the 3" neoprene cylinder into biscuits and sandwiched around a plate for the strut to attaches to. We then used a .25 spacer to bring the sandwich to 3.25" then welded the mount back together.

I think this may be the cause of a lot of 'unexplained' rear strut noises.

Thanks a lot guys, this thread has been helpful. I'll make sure to have all the proper hardware for installation (including the energy suspension bushing set).

Ohhh hahaha.. yeah man! When you install it drive the car for about another 500 miles max, then re-tighten the struts! It's like installing sway bars, when you install them, they're nice and tight.. but after driving and putting some strain on them, they'll more than likely loosen up a bit, sometimes not even noticeably but you should still re-tighten them, even if it's a thread. After that, they should be completely tightened down.

There's a few other parts in vehicles that will get loosened up after even if they were tightened well, and they'll only loosen up after a good amount of miles (facing all kinds of road surfaces if that makes any sense).

Kind of like re-installing a head, a lot of times you need new bolts after doing some head work, but you also have to stretch them by tightening with so much torque, then loosening them, then tightening again with even more torque, rinse and repeat til you finally torque it at the right spec.

Pretty crazy stuff, but ya.. always check suspension components after installing them about 500 miles +/- later.

I just did all of this and it did not fix the problem. Then I realized my sway bar bushings were bad
