Tonyx33 Oct 23rd, 03, 05:42 PM just rebuilt rearend got a new nut from gm goes all the way on with out getting tite anyboby else had this problem even got another nut from gm still the same thanks for the help davidpozzi Oct 24th, 03, 10:08 AM Tonyx33, I'm moving this message to the Transmission section. I think you will get better help there. this question is more of a drivetrain question than a suspension question. Good Luck, David TC Moderator Hugger67 Oct 24th, 03, 05:31 PM Tony, Hate to ask the obvious question, but did you remember to put the thick washer under the nut? dnult Oct 25th, 03, 04:09 AM Did you install a new crush sleeve? Tonyx33 Oct 25th, 03, 07:31 PM thanks for replys got it going Tony dnult Oct 26th, 03, 03:47 AM What was the magic bullet Tony? -dnult Tonyx33 Oct 26th, 03, 03:19 PM I though nut would start turning hard about half way no at the end thanks dnult Oct 26th, 03, 04:38 PM I'm not a rear-end expert and have little experience with them. But in general, I believe you install a crush sleve around the pinion shaft, install the seal, washer and nut and then torque the bolt until you have a specific amount of drag on the pinion. I don't think the torque spec applies to the nut as with most fastners. Basically, it's tight when it takes a specific amount of force to turn the pinion - say 50 in*pounds (pulling numbers out of the air). Somone please correct me if I'm wrong. Perhaps this is what you found out Tony. -dnult big gear head Oct 26th, 03, 04:56 PM dnult, You are right, tighten the nut untill the bearing preload is about 19 inch pounds for new bearings and about 12 inch pounds for used bearings. | ||
