rear bushings clunk
 

so i did the 20 min mod and new RSB bushings in the rear and now I have this horrible clunk. Is this normal with the 20 min mod (more of a rigid mount type of thing) or is it a poly bushing issue thing or is there another issue? I'm not an idiot here I know how to work on a car so I don't think it is my skills lacking so is this normal or ??????????

I got the rear bushings from Summit using the PN that is in another thread here somewhere. I reused the factory "U" mounts but I have to say that the bar doesn't feel that solidly mounted. Opinions?

photos of what?

You should use the brackets that came with the mounts, and a bigger nut and bolt.
8mm are stock, I use 10mms.

Great info! Thanks a lot!!!!!!! I will get some hardware and go to town on them asap and hopefully get this clunking under control.

Atleast I got the right bushings...(whew):lol:

When you say 8 vs. 10 do you mean length or ???

Photos of the sky.:p Photos of what this thread is about- the bushings. Remember?:D

Diameter.
A bolt is classified by the diameter of the threaded shaft of the bolt.
On a Subaru a 6mm bolt uses a 10 mm head, and usually
an 8 mm bolt has a 12 mm head, and
a 10 mm bolt has a 14 mm head.:)
25 mm long will be fine.

What "mod" had been done that created the clunk?

Mine has a rapid clunking sound slow speeds, rough roads along with terrible suspension squeak.

Has NEW rear strut mounts, but didn't change either noise.

are your sway bar bushings any good?

Re: rear bushings clunk
 

well I went out and put the U brackets that came with the bushings on. I used the hardware (nuts and bolts) that came with the 15 min mod stuff. The bolts are grade 5 so it isn't like they are junk and they worked great!

Anyhooo long story short I spent 1 hour in the yard under the car (no lift for us hard core types) :lol: and I got the job done and my clunk is gone. Sweet!

Thanks Tom for the advise and hopefully any of you folks who want to do some updating of your suspension see this and don't make the same mistake as I did.

I spray lubed anything that was rubber, or any kind of mount just to see if noise would go away...and it didn't.

It was frustrating, as I could lay under car, and pull down on the bumper and make the squeek happen while I sprayed and noise never went away.

I was thinking... Maybe photos of Summit?
