well i have not really been into my mustang too much lately, due to a few reasons and i need help fixing them!!

1. Rear end CLUNK, this is by far the most annoying thing i have ever experienced.

2. Rear end feels loose when i let off the gas

3. header rubs steering column, although i know how to fix this one.


So, for number one the rear end clunk... i dont really know why its doing this but i think it may have to do with the pinion angle, i never really had my pinion angle set correctly so when i let on the gas it goes CLUNK really hard and it feels like im getting alot of drivetrain slop.

i replaced my LCA bushings and its still there, i tried playing around with the pinion angle and it actually got WORSE, i extended the control arms a little bit so i guess i can try tightening them up but ive always had this clunk.

Maybe the driveshaft? now when it was summer i ran this car at the strip maybe over 50 times so i was also thinking maybe my UCA is loose.

now for number 2, its kind of subtle but also noticeable. if im cruising down the road say at 45mph in 5th gear... i press the gas maybe 50% and then let off, the rear end will 'wiggle' side to side very slightly but enough to annoy you.

when i replaced the LCA bushings it helped ALOT but its still there... maybe the UCA? but idk why it would go bad as its stock but then again i did beat the **** out of my car at the strip.


and lastly, i'm going to get some motor mounts to fix my header rubbing problem.\


but any ideas as to what i can do to fix it? How do i set the pinion angle correctly?

i was thinking maybe just go ahead and get UCA and a driveshaft to go along with the motor mounts and see if that helps but i would rather not as this moment.

bump anyone???

 

i'd help you kaldar, but i have no clue
as to what could be causing the clunk.

i know these bugs are annoying and i do
hope you get them fixed.

 

I would think if you are getting side to side wiggle on acceleration and or deceleration, to check the panhard bushings, which also might cause some clunking.

 

Hmmm... ill check out the panhard bushings, man i just wish it would drive normally!

i LOVE driving my stang but i wish it wouldnt have so many annoying issues

 

LCA's... lots of people have clunking problems with them. search is your friend.

 

mine do the same thing this is normal
I'm still trying to figure out how to make it go by by

 

so then what do i do and i dont think this is the LCAs lol

 

do you still have the stock lca's? if you do try putting them back on and see if it goes away, i eventually had to start doing this to pinpoint my suspension problem..

 

i might have them laying around somewhere, i really dont think its them because i can feel my wholedrivetrain slop around and i just replaced the worn out bushings on them
