rear diff problem ????????

[dentedfender]

i went to take my bent ass rear driveshaft off today and noticed that i can move it up and down, after futher investigation i found that the flange that connects the drive shaft to the diff moves up and down.  I was wondering how you fix this? Do i just have to tighten that nut or do i have to remove my 3rd?  Any help would be great thanks

Sounds like your pinion bearing exploded

Pull it!

that sucksss i just got that rear axle back together two days ago. do you have to have any speaical tools to replace it? all i have done to it is weld it, anybody have any pics of the bearing or the procedure of taking it out? i have some bearing laying around but i dont know what they are for they came in the gear box with the old gears when i bought the thing if i can remember some are unopened

Take the driveline off and check to see if the pinion nut has been staked to keep it from backing off.  If not tighten it and stake it in place.  Even if it has been staked its worth a shot to tighten it down snug and see if you can still turn it.  If its tight when the nut is snug then a bearing is toast, it should be a bit of resistance not hard to turn when its in its proper range.

it looks as if it has been staked but ill try to tighten it, aslo would it be way bad to drive it  like that because im have to go get measurements for my front drive shaft tomorrow?

Yeah, I'd give the pinion nut a crank before pulling it, you'll know pretty quick if it's a bearing after you tighten it. Don't try driving it loose though, the pinion will hit your carrier and start grinding on it.

I have the same problem with my front diff mine goes in and out and up and down and leaks, I'll pull your rear if you pull my front . If you don't have one already go with the solid crush sleeve while its apart.

When 6 of my rear pinion teeth broke off and got between the gears it wobbled like this too, I snugged the nut and ran it for 11 months.  When the guy I sold it to pulled it apart to rebuild it he said everything inside fell out.  Just sayin if you re-torque it and run it you'll likely pound it down to nothing leavin you stranded somewhere down the road...or trail.

i just heard back from my friend looks like my ring and pinon are shot  $300 later and then I'm back on the road.  That is if nothing else decides to pop up but I'm keeping my
