All these oil pump units are prone to pump chattering.
A case saver will not last longer then a simple build up of JB weld in the rub areas. JB weld will protect those spots and last longer then the savers any day.
Just changing the fluid now and then making sure it is not contaminated will make it last a lot longer and ward off the rub holes. These must use the GM auto trak blue fluid only. Anything else or dirty fluid will cause the pump to chatter more and burn holes in the case.
Yep, no slack adjustment.. We cut a viewing window into a junk case half to check the tension of chains. You would be surprised at how loose a new chain runs. So it isn’t a long ways between a good chain and a junk chain that will start to eat into the case.
A fast way to check a chain is to hold it on your hands and see if the ends will touch easy. Of lay the chain on the bench folded and see of the end meet. If they do its stretched beyond a safe use point and should be replaced.
My chain is starter to slip once in a while under load mostly in reverse. How much slack adjustment should be set. Can this be done without opening up the transfer case
@petem1948 - pete there is no tension adjustment that i know of, the only option for a worn chain is replacement. if the chain is slipping my guess you have a bigger problem. the transfer case controls the engagement to the front wheels, if the clutch plates are worn it would be most notable while the 4 wheel drive is engaged and front wheels are under load.
