Drive shaft lubrication help

[ilmfj62]

Hello, asking or assistance with this posting -- I do not live in the USA but I keep my 100 in storage in Raleigh. I'll be flying in to RDU on Dec 22 and driving to the Kernersville area. I have the issue described in this post : The OFFICIAL clunk/thunk driveshaft thread
However, I don't have the means to lube up the drive shaft on my own. I can provide the moly and grease gun if someone can apply to the drive shaft. I'd rather someone familiar with this do it rather than taking it to a random shop. -OR- if anyone can recommend a shop I would gladly take it there with the grease and gun.

I'll pay for the service obviously, so anyone alone the I-40 route willing on 12/23 please let me know. Thank you!!

If your chasing the clunk, driveshaft lubing will be at best, temporary. Not that you shouldn’t do it, you want to keep it lubed, but when you follow what that thread outlines, you just mask the issue.
By pressurizing things, you are loading up the diff a bit. This load is transferred to the diff mount bushings, and they then clunk less for a short while.
If you want the fix the issue, he diff mount bushings will likely need to be replaced.

I've heard of folks cracking their transfer case housing by overfilling the driveshaft with grease in an attempt to quiet the clunk. Sometimes the grease can't travel to the splines that need it because of a build-up of old crusty grease. What I do to baseline is to remove the shaft from the rear diff, mark the two halves of the shaft for alignment and then separate them. Clean splines on both sides (male and female) with a bottle brush and kerosene, diesel or mineral spirits to get all the old grease out. Smear fresh grease on splines by hand and re-assemble. Once baselined, three pumps of grease in the driveshaft zerk at each oil change should keep it running smooth. After pumping three pumps, remove the driveshaft zerk to let any excess grease out and to insure there's not too much pressure on the transfer case, then re-install zerk. As mentioned, diff bushings contribute to the clunk. Checking them for wear would be a good idea. I apologize, but I can't be much help to you as I am in Charlotte. Best of luck.

I read the first and last page of that thread but was gonna mention the same as the two posts above which offer great advice. Too much grease and youve set up a hydraulic ram on your tcase. And the redhead just posted his recent success with the diff bushing swap helping his clunk.

That said im in between RDU and Kville and could possibly help. But if you have the grease and gun then your pretty set to apply. Also if you have the time and wish to order the part in advance blackmons imports in High point could probably swap it out for you and separate/clean/lube the shaft at same time. He is cruiser friendly.

Worth verifying but that should be part #
