crush sleeve ?
crush sleeve ? i can't get the crush sleeve to crush. i'm using a impact wrench and it's still not crushing. do you think i need a higher impact? if i do how many pounds?
I've never gotten an impact to crush a crush sleeve. Usually I'll put a pipe wrench on the yoke and let it hit the floor or somewhere under the car, then get a breaker bar and a pipe to crush it.

I'm sorry, I'm feelin' like an *** today and just couldn't resist.I would think that using the long bars would give you a little more control over how much your sleeve is crushed.

Yeah...I have got probably a few hundred running around that are "impact crushed".

Guys I am not gonna get in a Pissing contest with ya . But you use a impact you will either over torque or under torque the crush sleeve. Depending on the rearend manufacturer you have a certain amount of torque that needs to be applied to get the proper crush on the crush sleeve. Which is checked by rotating the pinion, checking the torque to rotate the pinion in in.lbs.. Spacers are different if the thickness is spot on, impact won't hurt it . Won't catch me using impacts for assembling pinions. Besides with an impact you never know the real torque value. Disassembly no problem.
BTW for DynoDR and LS1Nova , I gave up counting the rebuilds in about 1980.

Roy I understand where your coming from, but I dont just recklessly tighten it. Just a couple raps with the impact till in starts to drag, then turn it with the inch pound beam style torque wrench and keep tightening until around 20 inch pounds of turning force is required to turn it. Everybody has there own way, I just feel that the impact way is less work.

Out of the few thousand differentials I have done, if it were in the chassis, it was done with an impact...... and some attention to detail. If it were a 'bench job' and the impact couldnt pull thru (like on some OE BMW and Nissan diff's or DANA 70/80's or 14" third's) they went into a 40Ton 2-stage press.
I normally use 14-16 rolling inlbs on used bearings and 30-34 rolling inlbs on new bearings with liberal assembley lube..... and the assembly lube has a lot to do with it as well.
I know where you are coming from...I am just being honest. And there a probably more "big name" rebuilders that use an impact also. I know a couple that will admit to it. Like said earlier...You CAN ease up on it with a impact..I can keep it within a few inch lbs rotating tq. Which by the way is how I check it also. Not pissing just after reading it I thought some may take it that we meen just "hammer it up tight" . ALL of us do plenty bearing jobs because some one with an impact that doesn't know any better did a pinon seal job a few weeks ago!!!
