HI all,

I had been having an issue with the rear of my truck vibrating when I was turning and/or accelerating from a dead stop. I had done a lot of research about having to regrease the slip joint in the drive shaft. I went to my local mechanic and he really helped me out.

he told me to just get a grease gun (which I had) and a "greasing needle" from autozone or such, and grease the slip joint . all I did was insert the needle into the joint sleeve and put about a half tube of grease in and all is good..

the grease seals the needle puncture when you pull it out of the boot sleeve.

I've been havin the same problem with my 04 f250. Did greasing the yoke help the vibration?

 

The best thing that I have found on my F-250 with 230K on the clock is to go to Ford and get a tube of "PTFE" lubricant.
Remove the drive shaft separate the yolk and grease by hand.
The Ford grease will last 6 months to a year or until you pull a really heavy load.
Tip; Get a six point 8mm socket or box end wrench for the U-bolts on the universal joint or risk rounding the bolt heads.
This procedure takes me about 10 minutes to do.

Thanks I noticed every time I pull my heavy camper the vibration gets a little worse but not unbearable. I hope this is the cause and I won't have to get into the posi unit in the rearend!!!

 

I had the same issue. I sent y rear driveshaft out and had it completely rebuilt. They also rebalanced it. I was surprised at the amount of counterweights they added to get it to balance. But I will say it drives like a completely different truck. Like brand new. And to think all this time I thought my rearend was going out and my tires were bad. Nope.
