[6pack] Clunky rear

[Sally or Dick Taylor]

Kendall---The axle splines can be lubed with any good grease. (I prefer that nasty black stuff, Molykote). Clean out the inner splines with an old toothbrush and thinner or gas, and the do the same with the outer half. Wipe or blow dry, lather them up, and slip them together. If you have both pieces in your hands you can sort of tell if the spines are worn, by doing the back and forth thing. You'll get a better look at some of the u-joints this way.  (I always suspect the 'joints)

As others have noted, you could have a stacked accumlation of play that can create the snap you hear. A new right side axle solved my noise, after doing the other checks. Swapping them around from side to side did nothing.

Do not discount (loose) lever shock bolts as a cause. It only takes a little to bang around. Check the bolts that secure the trailing arm brackets. 

If you suspect it's in the diff, take a drive "up the coast". I can loan you a rebuilt one. If that was the problem, we can negotiate a price!

Hey List,

I have a sporadic clunk in the rear end of my TR6 somewhere. I inspected the diff mounts and they don't look cracked anywhere. The stock shocks appear to mounted solidly. The wheels don't wiggle back and forth at all side to side so the hubs are at least in reasonable shape. I jacked up the rear and put the ebrake on and tried loading the drive train up a little bit in forward and reverse and couldn't reproduce the clunk. I am most likely to get the clunk when turning while pulling away from a stop. 

This makes me think that it is possibly the splines on the half shafts binding up. How should those be lubricated? 


Any other ideas for clunkiness in the rear? Possibly internal to the differential?
