GMC Jimmy wheel bearing removal
Question:
1998 GMC Jimmy 4 WD front wheel bearing replacement. I got the brake off and supported. Took the ABS sensor off. Removed the hub nut after getting a 38mm socket, and removed the 3 bolts from the back side of the bearing hub. I then hit it with a hammer and after a few hits it broke loose. But its still connected to the drive shaft. I figure I must need a puller to get it removed from the spindle. Am I right or wrong again LOL. Tim

again You need to tap the axle shaft out of the bearing and hub assembly. Just be careful that you don’t wreck the threads on the axle shaft. If it’s badly siezed you may need a puller, but I’ve always been able to get them out by just tapping on the shaft with a brass drift and hammer. Ian
Response:
Just to make sure I do this right. You are saying I should hit on the threaded shaft that had the large 36mm nut on it. I am being careful not to add extra expense by doing something wrong. After I get this one done I have another to do on our second Jimmy.

Yes that is the part to hit >>>BUT DO NOT HAMMER DIRECTLY ON IT<<<. Put a small block of wood/plastic on the end first, or use a rubber/plastic hammer. If you hit it with a standard hammer you will end up either damaging the threads the first time you hit off center, or mushrooming the end just enough to prevent you from putting the nut on again. — Steve Williams Near Cooperstown NY – Hide quoted text — Show quoted text -> Just to make sure I do this right.

Yes, that’s where you will have to hit. As another poster mentions, you don’t really want to hit directly on the end with a hammer. There is a section right at the end that doesn’t have threads, but it’s really much too easy for the newbie to end up damaging the threads badly enough that you would need a new shaft. A brass drift works best, but most folks don’t have one of those. Another option is to re-install the nut and screw it in just far enough so that it is slightly past the end of the shaft. This helps to prevent the end of the shaft from becoming deformed. If the shaft is not that tight in the bearing, it will come out quite easily. If it’s very tight, you so run the risk of damaging the end. Good luck. Ian

I placed a 2 X 4 on the threaded spindle and hit it over 20 times with a 2 pound hammer. I called Auto Zone they have a two loaner tools for removing the hub. One is a 3 sided puller and other is a slide type hammer. I know that the puller have used them before and have a good idea of what the slide hammer is. My question is what is the best to use. I am worried hitting will cause other problems or should I just continue till it comes off.

I got it off the slide hammer would not work. Got the three side puller. Just took some time to turn the screw on the puller, hit it with a hammer, and even put some heat on it with a torch. It came off HARD all the way. – Hide quoted text — Show quoted text -> I placed a 2 X 4 on the threaded spindle and hit it over 20 times with a 2 > pound hammer. > I called Auto Zone they have a two loaner tools for removing the hub.

I am doing this exact job today – great timing for a post. Something no one has mentioned yet… What torque do I put on the hub nut when putting it back on?

Response:
Not idea what the torque is. I did put the hub about half way and forgot the splash guard for the brake and had to pull it back off. Auto Zone told me it should just slide off. WRONG they come off HARD and go on HARD even after a good cleaning. Good Luck. I have 3 more to do.

Done….not a bad job (4 hours including lots of learning). The car is 80% quieter now…but something else is grinding. I wonder if the other side (front) bearing is going too. What’s strange is that the noise appears worse with even a slight turn left OR right. Given I just replaced the right front bearing, do you think it is the other bearing? (Do you have the same symptoms) or do you think a CV/U joint is to blame? Thanks, Mike – Hide quoted text — Show quoted text -> Not idea what the torque is.
