Cherokee transfer case forks broken
I've got a '99 Cherokee Sport with ~90k miles. I was recently driving
in 4wd at around 80mph on a wet highway when I experienced a couple of
bumps from somewhere in the drive train. It felt just like a hit some
rough pavement, in fact that's what I initially thought had happened. I
got out and walked around the vehicle after feeling it again and
realizing that it wasn't the road. I saw nothing out of the ordinary.
About thirty minutes later I got the bump again followed by a horrible
grinding noise. I quickly slowed down and threw it into 2wd. The
grinding stopped, but I'm still getting intermittent bumps. The bumps
vary in intensity and frequency. It basically feels like the vehicle is
being bumped from behind or hitting a large pothole.
So, I took it to a local transmission shop and they opened the transfer
case. They're telling me that the problem is a broken shift fork. The
fork needs to be replaced along with some damaged bearings. Does this
sound right? I don't know much about 4wd since this is my first, but I
fail to understand how this happened or how it was causing the
bump/lurch/jerk. They want to charge me $900 to do this work which
seems steep. Again, I don't know what I'm talking about, so maybe it's
not steep.

Re: Cherokee transfer case forks broken
Which transfer case do you have? If you have a part-time transfer case
("Command-Trac" or NP231), it is not designed to be driven on hard surfaces
at all, even if the surface is wet. Snow, sand, gravel, dirt is OK, but hard
surfaces are not. The full-time "Selec-Trac" or NP242 can be driven in
full-time mode on any surface.
If you're somewhat handy or have friends that are, you can find low-mileage
Jeep transfer cases on ebay for a couple of hundred dollars (including
shipping) and install it yourself in a day or 2. $900 sounds quite high to
me as well, just for replacing parts.

Yes, it sounds right. If you can do 80, you should not, that's NOT, be in
4WD. You exploded your tcase. While they are putting in the obvious parts,
you may as well get a new chain and sprockets too.
