8.8\" LSD pinion shaft

i took the lockpin out and rotated carrier 180 and the shaft didnt just fall out in my lap like Haynes would lead me to believe... what am i doing wrong? the side/pinion gears are chipped pretty badly, would that make a difference? i found pieces of them in the bottom of the housing [img]images/graemlins/blush.gif[/img] do I have to do something special for the LSD carrier? btw, a leaky passenger side seal prompted this, are there any tricks to changing those seals or is it straightforward? grrrr

Re: 8.8\" LSD pinion shaft

you removed the bolt correct? the whole bolt? the bolt goes way past where the threads are and have a tendency to break right at the end of the threads. sounds like that could be your problem. if the whole bolt came out give the thing a pound through from the other side as its propablly getting hung up on the scratches in the shaft from the busted up spiders.

Re: 8.8\" LSD pinion shaft

yeah, the whole bolt came out. probably just needs a tap. also, can i reuse the lockbolt? Haynes said some kinds have to be replaced, but wont it be ok with some loctite? time for a 1 ton, these inner gears are ate up! [img]images/graemlins/cussing.gif[/img]

Is that a "torque to yeild" type bolt?
If that's the case, it should be replaced.
(I know, they're generally head bolts, but ya never know.)

Sounds like with the amount of people that have broken that bolt, a new one would be cheap insurance.

Got in mud....lately? [img]images/graemlins/grin.gif[/img] [img]images/graemlins/givemebeer.gif[/img]

Re: 8.8\" LSD pinion shaft

ok, got that [bleep] out, now how does this mother umping wheel bearing come out? i've successfully sent the inner cage, rollers, and part of the seal into outer space using autozone's loaner slide/2jaw puller, but i cant seem to get the outer cage out. is there a ledge behind the bearing thats part of the housing? cuz i've been sliding HARD but the damn thing wont budge, so i think i'm pulling the wrong thing? it's weird, because it almost looks like the seal is part of the outer bearing race, does such a thing exist? my replacements arent like that. this sucks, why cant anything be easy? grrrrrr i'm done for tonight, my friend has 36 pilsners to be had, and i'm going to down those fawkers like never before. bye.

Re: 8.8\" LSD pinion shaft

Mine had a 1" long rod behind the bolt , it dont appear to be part of the bolt but what i did was magnetize a small drift punch and stick it in the hole to extract it...

Re: 8.8\" LSD pinion shaft

I picked my seal out with a good quality screwdriver then pulled the brg. I know that the axle repair brg kit (for when the original spins in the housing) is a one piece unit seal & bearing, maybe someone previously had to install one? There is a small lip behind the outer brg. shell in the housing, actually a stopping point i guess so it cant go in any further, but it should`nt stop you from getting a grip on it unless the puller is a real piece of [img]images/graemlins/cussing.gif[/img]

Re: 8.8\" LSD pinion shaft

Steve and I busted the bearing apart and used a three jaw puller and a slide hammer to get the bearing case out. The bolt to which you spoke of is about two inches long with only about 1/2 inch or so threaded. Ford carrys them for about $1.00 each.

Re: 8.8\" LSD pinion shaft

I looked at that bolt when i took mine out and it appeared that the ends (threaded and the rod) were smooth not jagged as if it had broke so i assumed they were two parts (one of which the Haynes didnt show) , but Now after this discussion, im nervous [img]images/graemlins/blush.gif[/img], i put the two parts back in and used lok-tite on the threads, is my rear gonna grenade on me someday [img]images/graemlins/shocked.gif[/img], apparently that bolt HAD been broken for some time though, my rear cover has never been removed prior to me pulling it off recently.

Re: 8.8\" LSD pinion shaft

I had problems getting my beearings out too. I was using the zones 3 prong slide hammer and worked on it for like an hour with no luck. finally i got pissed and seriously went ape sh!t on it and it came out. but not before sending the bearing rollers into orbit as you did. [img]images/graemlins/bs.gif[/img]
The trick that i found out was to move the slide hammer handle a couple degrees in a circle each time you hammer it. eventually i was able to work it out. After I figured that out the other side was easy.
