BenzMac, Thanks for the word on using mid grade.
My G has 115k miles. Fluids have been changed regularly. Tuneup and engine rubber completed.

How do you check the wheel bearings? Or should they be put on a PM schedule and changed every XXk miles?

Diff locks work great, but getting them to engage can be tricky to downright stubbborn. Especially when its cold. Following the manual to the T so as to not break something expensive. Any thoughts?

Getting ready to change out the transaxle mounts and possibly the auto transmount. Next will be the exhaust. Going for a TimeValve stainless. Looks like the gas tank has to be dropped.

Would appreciate any comments on anything I've written here or things I should be looking out for.

Just finishing up my first ownership year.

Thanks, J.R.
