Tranfercase Grinding and Squealing

Post by Horsehammerr »

After replacing front CV axles and Hub bearings , I find out the Squealing and Grinding is coming from my Transfercase. Works in 2wd, 4wdHi, and 4wdLo, but man what a racket ! What could this problem be ? I have hardly ever used 4x, what can I do ? :?:

Will an '03 ZR2 transfer case fit my '02 CC ?

It’s possible something let loose inside. I believe the 236 is more problematic than the 233. Which do you have?

:?: I have a 233C in mine and have located one out of the same truck I got my ZR2 rear axle assembly from. That's right , with only 179 miles on it. I call that NEW. Just seems strange that my Transfer Case would Bust the day after I put the "NEW" rearend in ? Beat Midwest Trans by $300 :roflmao: And Thanks for the Reply STUCKY :bow:

Yea stupid prices on that site, but good info and pics.

Did you check the fluid level? Or for leaks? There isn’t much inside a 231 or a 233, but a 236 looks scary inside. I’m wondering if the tube came off the pump or if the pump is wearing a hole in the case. If you had the case off, a good set of snap ring pliers, and I believe a 10 and 14 mm are all you need to take it apart and see what happened.
