68 Rear Wheel Bearings - The 1947 - Present Chevrolet & GMC Truck Message Board Network

CareTaker · 09-07-2005, 10:18 PM

Have a 68 GMC pick-up that has blown rear seals in the axel. I have some concern with the rear axel bearings being shot as well. According to the book there are three kinds of bearings: drop in (easy to do), press in (still easy for me to do ), and machine pressed in (need to go to the dealer or garage to have them do it).

My question: how can I tell if the bearings are press in or machine press in. Short of wailing on it with an impact hammer and seeing if I can get them out?

Many thanks!!

I am awaiting feedback on your question also. Since the axle housing is not removed normally, I guess that a 2 finger inside bearing puller will be needed, then to install the new one---use a bearing installer or a large socket to evenly tap it in. It should be a flat roller type. They do make a repair bearing if you have surface wear on the axle. I think it is p/n RP6480.
