Clunk free driving....yeah, right!
Done the driveline grease job and I can see why it will be "clunk free". Had to hammer with force to put the female part onto the male splines. Why would this need be? All your doing is putting a film of grease on the splines. The splines weren't that dry when I pulled it apart with ease but going back together was a wholw new game! Any of you that have done this had to hammer the parts back together? Well any way, it's "clunk free" now. Just hope it doesn't wreck the seals on the differential or transfer case as it couldn't be move at all by hand after assembly.

Trakman, Finally,
I don't want to rain on your parade but this came to mind when I read this post. I've built alot of driveshafts for myself and friends that I wheel with. Sometimes there are single thick splines on the yokes and driveshafts. If you weren't watching that could be easy to miss. And you can hammer the shafts together when it's not indexed properly. It's kinda like a keyway. When I find my friends have done this, I have to go back in with a file and straighten out the splines they messed up. They generally slip fine after that. But if you keep driving it like that it will chew itself up and you don't want that. I know you just got it back together, and probably don't even want to think what it's going to take to get that yoke off, but I would pull it back apart and take a closer look. It happens way too often. And if you think about it, if that yoke doesn't slide easily on a greased surface, there is a problem. I would just check for an indexing spline. Just my 2 cents.

Well I noticed the "indexing" spline on the yoke part but I could not find one on the shaft...looked and looked....felt lt it and just couldn't determine that there was one...would have thought so but was getting frustrated and now that I think about it, if there is not one on the shaft then you would have one spline "cutting" it's way through the blue teflon that has never seen a spline from factory assembly. Get my drift??? Anyway, short of being welded together after hammering it on, Its "clunk free" for the time being!

Well this driveline is about to drive me nuts!!!! Was told this morning that I need to make sure that the u-joints are in time, which I never even give it a though and after looking, sure enought it's off by a few splines, sooooooo It's back under the truck and drop the line, beat it off if neccasary and time it. What a bite in the A$$! Can't believe that a 25min. job has turned into a piece of ***** like this! GGGGRRRRRR!!!!!!! Hope that the next person here on the board that needs to do this will learn from my mistake!

Is this the front or rear? I have a bad clunk when hitting bumps with the front end. I just put new sway bar end links and sway bar bushings in and the sound is still there. Is the next step to grease the driveline?

The driveline is the last thing I can think of that would make noise.

FINALLY...yea!
Here's a follow up on what happened after I dropped this "clunk free" driveline. First, I thought I was off about 3 splines to have the u-joints in time. Grabbed the brass hammer and beat the yoke part off...and I'm here to tell you, it took alot to get it off but finally, success! Before removing the yoke, noticed that the welded yoke on the tube wasn't anywhere near in time with the yoke I had to beat off. Was told by a mechanic this morning that this is very important also....so in essence, instead of being off 3 splines, I was really off about 10 or so (90 degrees). Relubed the splines, lined things up and it slide on with ease!!!!!....No hammer needed....sooooo, you guys that did like me and beat the yoke on....an absolute no no!!!!
Hope this helps some of you guys. I have my sanity back now and feel real good about this lube job.

Ditto, on that. It didn't take but a couple taps to get my yoke off though. So I regreased and tried each spline until it went on with just my brute strength (not a whole lot). I will have to check the alignment though.

Speaking of driveshafts......
I've been doing the "lube the spline" thing on my '01 F250. The other day I noticed the boot has exploded at the spline joint and no longer protects the spline. Is there a split boot replacement for this or will I have to take the joint apart ?? The rearend u-joint has not been away from the yoke since new and the joints are all tight and quiet. Any thoughts.
Thanks
