Rear end slop

[95f350powerstroke*]

So when I take off from a stop or my trans is all locked up rolling down the road I feel a thud, like a sloppy u joint even though it isn't. Is there a way to shim the rear end gears to tighten them up? Or any solution?

I have the same problem. If you let it idle enough up to speed you don't get the pop right? But under normal take off and acceleration you get the thud ot pop as you begin moving right?

Ill be following this to see what all is said! Good luck!

Exactly! After tooling around a little just recently after making this post, I found that some off roaders running this axle have had pinion nuts either being loose or the splines being worn down and causing the slop.

You can shim the pinion gear, but if there is very much slop at all your gears may very well need replaced. especially if you have been driving it much with the slop. Ive got a dana 44 in a jeep that started to get sloppy and by the time I worried about it their was no helping it.

So if I replaced the gears you think it would take care of the slop?

Do either of the first posters have a carrier bearing in their systems? If it moves then it's time to replace.

No sir I don't

With the truck off and in neutral (tires blocked) is there any play in the drive line? No twisting action, no up and down movement (on the shaft, transfer case, or at the pumpkin), and the support bushing on the transfer case is good (not melted, rotted, dry and cracking)?

Well Maybe not so much the gears but deffinately the bearings (pinion most likely) but if there is much slop in the pinion due to bearing wearing out, the ring and pinion could probly stand to be replaced.

After bashing on rock crawlers and trail jeeps I learned sometimes your better off to replace it all. haha

I've got the same slop in my drivetrain. A slight clunk when applying the go pedal, moving or not. Have yet to track it down. Figured it was in the rear end.
