rear pinion bearing dana 35 1997 jgc 4.0 np242

Hi this is my first post. I have a 1997 jeep grand cherokee with a 4.0 I6 its an automatic has the np242 tcase dana 35 rear and dana 30 up front. I believe it has 3.55 gears. Im told i need a new pinion bearing for the rear. I had the front done last year. Its making a loud whirling noise from the rear and I had the wheel bearings done at the same time as the front along with most of the tcase bearings. My issue is I can not find out which kit is right for this diff some have bushings others a crush sleeve? So im lost. . I was hoping some one could help me find the correct kit for this dana 35? Ty so much.

Your answer and availability can be found via Mr Kolak. He will probably chime in here OR you can search his username and PM him.

One stop shopping (-:

Good Luck,

Have you made sure the rear diff. has the proper amount of fluid in it? I had the same symptoms, it turned out my rear diff fluid was low, refilling it solved the issue. All you have to do to check the level is pull off the rubber plug on the diff cover, the oil should be level with the bottom of the hole. You may in fact need a new pinion bearing, but diff fluid is easy enough to check. I second Kolak for the part if you do need it, I've never heard of someone having a bad experience with him, and his parts seem to be the least expensive of anywhere you can get them.
