Title: Grinding in 4x4
Post by: jandh on June 04, 2009, 08:40:44 PM

Hey everyone, I have a loud grinding sound coming from what i am assuming is my transfer case when I am in 4x4 and step on the gas hard.

When I'm just cruising there is no sound but if i give her the gas when it revs up there is a lound grinding sound almost like two gears slipping off each other.  has anyone had this before too?   I was thinking maybe it the Chain in the t-case slipping.  What do you all think?

Any help will be MUCH appreciated with that 101 coming up soon

Thanx

I have a 89 XJ 4.L auto i think the t-case is a 241?? sound right?

Its most likely the 242 Tcase.  Is the linkage adjusted correctly?  It could be slipping a little bit if its not fully engaging.

Could be u-joints as well... have to hear the grinding noise.
grab ahold of the drive shafts, and give them a shake.

The U-joints seem to be nice and tight
The first time it happend i was on a turn, so i thought it was binding, so i checked the u-joints,  but it happens everywhere. so now i'm worried

  how can you adjust the linkage?  is it like adjusting an auto transmission linkage?

Looks like you nailed it.  I checked everything everyone said here except the t-case chain, and i treid to replicat the problem and it wouldn't do it again, I noticed the linkage is out a bit, so i must not have had it all the way in 4x4.

Thanx everyone for the help
Hopefully there is no problem at all  :)
