Clunk when Shifting

[jwebb]

Noise seems to come from the right rear, I've check the 3 link everything appears tight, banana bracket clears the 3 link bar by about 1/2". Could the lower control arm bushings be worn or damaged, have a little over 1000 miles. They are the cast aluminum version.

Jwebb: I had the same issue with FFR 8317 during the "primer stage" of its life...clunk when shifting and when going over medium to larger bumps... I found one of my gas tank support straps loose! (Doh!) Just sayin' :confused:

Does it only happen as you release the clutch, or, when applying power after it's fully released?
Does it happen on downshifts as well?
Did you try to see if it happens when you step on, and then quickly let off, the throttle?

Check the three bolts each that hold the brackets onto the bottom of the axle. Admittedly, it was due to running R compound autocross tires, but I ended up tack welding my brackets.

Check your U-Joints at the pinion and check your pinion backlash...

J. Miller,
Pinion backlash wouldn't change over 1100 miles or could it? I'll take a look at the u-joint.

[j.miller]

It sure could....those suckers could back out if they weren't torqued proper or checked.....I know this one first hand....mine was the U-Joint.

Me too, mine was the driveshaft flange bolts to the pinion flange (didn't use loctite at first)

[jwebb]

Turned out to be loose flange bolts, all set now !

Cool! Nice easy, free fix!

You did use Loctite?
