Question about 1994 Jeep Grand Cherokee

1 Answer

Transfer case knocking

I just replaced my transfer case in a 1994 jeep grand cherokee limited all time 4 wheel drive at 100k miles. Im sitting at 120k miles and it's making the same noise as before, but only when i first start to drive it. After it warms up the noise seems to go away. Could it be something else? I don't want to replace the same part again.Suggestions?

    In those transfers, mostly the plastic pump would break and start to knock, I would take it to a transmission repair that does free estimates, most do. And even the one who repaired it the first time.

These transfer cases do not have plastic pumps. Do have the transfer case looked at by Jeep tech, it could be as simple as an adjustment on the lever.

My 4 wheel drive no longer works.


WJ jeeps.
what mode? 4h, 2l lock >?
why not just drive it and get it all loose and happy first.
get the gearlube hot, see if it wakes up, i bet it does.
there is no vacuum hose. that is part time. used long ago.
vacuum ended in 1995 with command trac.
the newer cars the front axle is cut out, inside the transfer case front end. ending vacuum and now electric.

Select track (stay off dry pavement in 4wd)
Quadra-Trac-II NV 247 Gerodisc system 1999+
Quadra-Drive NV247
if quada stay out of low or lock.

read this page,. and discover what you have.
or go under car, see that transfer case, see that silver and red tag
that is the NV number. what is yours>?
we can not guess options. ever.

Where is the 4 wheel drive switch located on the transfer case I have a 1996 Jeep Grand Cherokee


If it is a limited, it doesn't have a switch. They are full time 4 wheel drive. A regular Grand has the 4wheel shifter right beside the regular gear shifter.

I need to find out how to tow a jeep grand cherokee limited with full time 4 wheel drive all 4 wheels down behind a motor home. I hope you can help me. Thank you


You can tow in with the transfer case in neutral as long as all 4 wheels are on the ground like with a tow bar.If you use a tow dolly you will have to remove the rear drive shaft.This transfer case has a viscous coupling that will over heat if all the wheel dont turn at the same rate.

Computer light says service 4 wheel drive switch


According to the mechanic who works on my 94 Jeep it's one of three things:
1) Corrosion on the connector to the switch (which is located on top of the transfer case).
2) A bad switch. Part cost about $22.00 or,
3) A bad console display. he says they have had a fair number of console display units fail.

Transmission quit moving no noise, nothing grinding etc..


If it doesn't move forward or backward, then the pump or torque converter are likely bad. First put it in drive with the rear wheels up. Pull out the speed sensor in the overdrive unit( rear housing on the trans) and look in the hole to see if the output shaft is turning. This will tell you if this is a trans problem or a transfer case problem. If it is turning but the rear drive shaft isn't, inspect the transfer case. If the output shaft isn't turning, hook up a pressure gauge to the transmission and check for line pressure. If line pressure is low, replace the pump. If line pressure is good, replace the torque converter.

4 wheel drive not working


sounds to me like the transfer case clutches are worn out. also the fluid could be low or dirty. try draining and refilling the transfercase with clean fluid. if it is still not working after driving it around for a few miles then you may need to replace or overhaul your transfercase
