So Im thinking I either need driveshaft spacers, half shaft spacers, or both. I am 13" from hub to fenders (so 1/75"-2" lower than stock) and when reversing I hear a clunk coming from the rear of the car. I check all my torque specs on the coilovers and a-arms, and they're all good. About to run outside and check the driveshaft for play, but wondering if there is something else that I could be missing.

Jacked the car up on the passenger side, crawled under, and tried to move the driveshaft forward and aft. Very slow slight movement from the exterior portion of the shaft, but IIRC that's normal as the exterior shaft floats on the inner shaft. With the car completely on the ground I cannot reach it though.

I do not detect any abnormal vibration though.

Definitely related!

Have you done the axle nut TSB?

 

I fired a PM off to the previous owner. I've never performed it.

EDIT: Upon further inspection, there is zero sign of the axle nut being restaked. I'll go buy a socket tonight and git er dun

 

I tightened the axle nuts tonight. The driver's side was considerably undertorqued. I was able to break it with almost zero effort using a 3' cheater bar. Will be taking it for annual tech this next Saturday. Will report back.

 

Well...still hearing it. Ordered the megan racing spacers today.

 

Did you tighten the ball joints correctly? Were they worn? Ball joints clunk when they are worn or loose.

 

Nope...just had an inspection last week and all 4 ball joints are tight with no play.

Apparently the Megan spacers are recalled so I was just refunded. Sent a PM to THMotorsports but havent heard back from them in about a week.

 

Doubt its anything related to axle spacers being the resolve. Your axle itself could be fubar though. You have two joints, one on each end of the axle. Bearings could be blown out on either end, but leaning towards the hub side based on the noise. Unless your inner cv cups are severely worn and or roller bearing hashed/broken, its likely not going to be the noise culprit. You would be experiencing severe vibration at that point if it was, and your not. So I'm still thinking axle nut, wheel bearing or hub end of axle joint. I suppose we cant rule out the diff itself yet either.

 

bearings were checked last week. All good there.

 

A couple possibilities are worn out diff mounts or engine mounts.
