hi all again and thanks in advance.

i found the problem with the front noises. the endlinks were tightened and the bolt for the strut mounts were tighted.

now in the rear, when i go over bumps, it sounds like something is loose and clanking around.

anyone experienced something similar?

again, all i did was get eibach pro springs, tokico d-spec and 20" torque thrust wheels...

thanks very much guys!

 

Check the clearacne between the panhard bar support and the over axle pipes. When you lowered the car did you repalce the panhard bar with and adjustable one?

hi o6gtrad! thanks very much for the reply..

yes, i changed it to a steeda adjust. panhard bar.

does it require further adjusting??

 

As long as you adjusted it to center the axle it is fine.

Richard

 

thanks rich...

im not sure what the noises are....when i go over bumps..i hear somethng loose clanking around the back....

like something wasnt tightened up...

 

Check the panhard support and the driverside over axle pipe. If there is less than 1/4" clearance I would replace it with the CHE Upper Support it is the ONLY one that was made correctly. Trust me I have tried them all.

Do you have an aftermarket over-axle exhaust? If so, recently installed?

 

lol u and your clanky mustang.

 

Check the exhaust hangers that are welded to mufflers...where they slide into rubber hangers...there may be a bit sticking through...if its too long...it hits the drivers side bumper rienforcement...happened to me...especially after it gets hot...system expands. You may have to cut a small amount off hanger...one closest to back of car...sounds nuts...but that's what made my noise

 

That's what I was leading to..

 

Mine made a noise when i would brake abrubtly. Turns out it was just the spare tire and jack which wasn't tighten all the way.

 

hi taco,
its STOCK exhaust...

 

hi fman, that is interesting. could it be as a result of lowering the car, the exhaust hangers can be hitting the inside of the body??

i should have a look...

thanks!

 

hi taco,

thanks for this...maybe since i lowered the car this is hitting the inside of the body..

i will have a look..

 

Check the rear sway bar bushing mounts that they disconnected to lower the car. Seems all the sway bar bolts on these cars love to come loose without loctite on them.

Is it only clanking over a bump or rattling under acceleration?, and does it clank with the car both in gear on a pothole and/or at low speeds(like a speed bump). I would say its either a sway bar loose in the back(just like the front) or if there is a clearance issue with the over-the axle pipe-which there shouldn't be with the pipe turned the right way(are the mufflers perfectly straight and centered?). Is it a sharp thump/clank or a hollow sounding one(like something hitting the body 'thunking' or the hollow exhaust 'twanging')?

.

 

hi kevin! thanks very much.

only over bumps do i hear this. speed bump for sure...

hmm...im not 100% sure the stock mufflers are straight.

its hollowing sounding...

any insight?

thanks again!

 

Mine does the same thing every once in a while. Sounds like something is bouncing around in the trunk.

I did install new Steeda stock front struts and rear shocks. That helped some.

Believe it or not it is the rubber things between the springs and the body.
Replace those with better quality stuff and the sound will go away.

I havent done mine yet.............but will.

 

hi GT john,

hmm...interesting...that might it also. are you referring to spring pads? i guess i dont remember if stangs have them in the rear.

any more info on that would be great!

Yep, thats them...........rubber spring pads.

If ya jack your car up and look up in there you'll see um.
