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.

Answers :

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
