I am looking to replace my steel drive shaft with a 4" aluminum one. Any thoughts on advantages or disadvantage? I am looking to reduce the drive line "clunk" for one thing.
Normal to HAVE A LOT OF LASH ON A TRUCK with leafs. My buddy and I used to call this "Ging-Gang!" Our 67 chevelle BB 12 bolt had a fair anount but bevr gave up the ghost - but my 69 Fairlane 500 with a 9" died.
Measure how much lash is in the 3rd member and see if its w/in chevy specs - if out, chevy should remedy, otw U live with it. IIRC, they allow for a fair degree of lash.
We see this at the dealership fairly regularly. Your truck likely already has an aluminum drive shaft unless it is a regular cab. It is under warranty. If you take it in the dealer will lube it up and it won’t clunk for a few months. There are few permanent solutions to the yoke clunk. The reg cabs and the v6 trucks don’t seem to exhibit the issue but the V8 crews and ext. exhibit it commonly.

Typical stealership. This issue is well known and in our fleet we solve it for good with one application of synthetic grease. But only our older Pickups have ever had this. For some strange reason our 3500 extended vans never do.
I wonder if they even tried to lube it?
Third Member refers to the rear end. It is common for them to have quite a bit of lash.

You need to sand the yoke and splines with 400 and/or 600 grit paper. Then use a lube known to work on these problems.
I sanded mine, and then sprayed on about 10 coats of Moly Film from Kano labs.....let that dry over night. And then slopped a bunch of Lithium Grease on it.

Not sure why you're under the impression that an aluminum drive shaft will fix this problem.
Heck, you might as well install a carbon fiber one. I've heard they're even better.
X2. If it's a yoke issue, the driveshaft material is irrelevant. I have solved this issue on previous GM and Ford trucks with the aforementioned synthetic grease on the yoke splines with a bit on the seal surface.
A large number of these trucks come from the factory with aluminum drive shafts and exhibit a similar clunk. I can assure you that if GM found that all that was necessary to resolve such a common compliant was a change in drive shaft material they would have done so if only to save the copious amount of warranty pays. Especially since they already produce so many in aluminum.

Lube no help.
thanks
So sorry, but if lubed CORRECTLY (as stated above repeatedly) this is gone and never comes back, at least 100k miles or more IME. We have a lot of these. Please save your money!
It's so easy to fix. But I'm sure a stealership could find a way to fail...
