Having problems with your GMC Jimmy ?
1998 GMC Jimmy 4.3L has started a slight lower engine knock. I read bearings, is it worth while to pull the engine and replace the bearings? 155,000 on the engine, otherwise ran great till now.
If you are going to go to the trouble to pull the engine, do a complete rebuild. If you are sure the bearings are bad, you may be able to drop the oil pan and replace them without pulling the whole engine.
I wouldnt bother with the bearings. i would replace the engine. even if u got a used one from a junk yard
