so! just when i thought i had almost finished breaking the voodoo spell...
90% of the times that i reverse,(in 2 wheel drive) i here a howling noise in the rear. its more noticable when it gets cold and worsens when i switch to 4x4HI and LO. it does have a pattern to it (like every full rotation it howls for a full second) maybe carrier bearing? wheel bearing?

I need to get this fix ASAP!! Snow is already here, and we are getting bombarded and i really want my 4X4 working properly, thanks in advanced

 

Usually you find it to be the pinion bearing but only one way to find out.......

 

hmmmm... maybe this is why my driveshaft broke off in both ends and not in half???

 

Dude you are having more trouble out of that truck!

anyway, weed hit it on the head I think. Mine did the same exact thing and thats what they replaced under warranty

 

OH I KNOW!!!! bro. im not even gonna modd it anymore! like i said before, this is going to be my winter/work truck and my new rig is going to be my sport/street truck for the summer (05 hemi single cab)

Would it be hard to replace my self? and is it expensive? or im i better of having a pro do it?

note: I've never touched the rear end when comes down to mods or repairs.
Thanks guys!

 

I think it would be best to leave to a pro if you haven't done diff. work before. You said it only happens in reverse, how fast are you going? I know my rear end makes some noise in reverse, but only when I really get some speed going, just backing out a parking spot and I don't notice excessive noise.

 

I always assumed that was the LSD chattering.

 

Sounds CHUNKED, sorry bro.

 

speed? ummm. like 5mph? i back out normally never back out in a rush.

 

I had a bad pinion bearing on my truck, I just swapped out the whole diff for one off an 07 Ram. Cost me $300~ took about 12 hours and I'm very inexperienced
