Rear End Help Quick Please!


Recommended Posts

Posted

hello this is my first post and i need help please i just blew up my rear end i got it all installed by my uncle who has set a bunch of them up. the problem is we set it up and put a used carrier posi and limited slip in it and new yukon ring and pinion, new wheel bearings and wheel seals. the problem i have now is when i deaccelerate and turn right it makes a kind of whirring noise that is consistent with the wheel speed. when you go straight or turn left there is no noise. when the noise occurs if i apply throttle the noise goes away. to me this noise would indicate wheel bearings but they are brand new timken bearings!!! the truck sounds fine going down the road. let me list some things that ive already tired, additive for possi, rotate tires, tried to get possi to kick in to get the additive in the clutch. I have a great deal of mechanic experience but i am just lost on this and i need you guys on this one!!!! any help would be greatly appreciated!! thanks CODY

+1, this is our way of say welcome! :(

 

As for your problem, it sounds like your carrier. Did you check the wear pattern on the gears? And was the LSD/posi unit/whatever you used replaced when you "set up" the new system? The unit itself might be worn out.

yeah the wear pattern looked normal i put the thick yellow grease on it to see that the pinion teeth were centered with the ring teath, pinion pre load is good, and backlash is normal, the carrier came out of a low mileage truck that sounded normal when it came out. how could i tell if it is the carrier? thanks cody

Ok guys latest news i just looked at my carrier. I shook it and I noticed just a little bit of play back and fourth on the carrier I mean barely anything noticable I know this needs to be fixed but could this make that noise? I mean I know it could make that noise but only with no throttle and when i turn to the right? It makes no noise when I am accelerating. Thanks, CODY
