So i went to dealer today to see service records on it. since new it has had all services done at same dealer up to 130k. some things i noticed were handles done under warranty, also had rear shocks done @ 115k, and something emmissions related at same time. I also took it on a 250 mile round trip today to get some jeep parts. things that have me worried are oil pressure at idle it was around 15psi according to gauge and about 37 running at highway speed, is this normal? it is almost due for a change and i checked it and it wasent to low. also depending on how i started from a stop there was a clunk from the rear, not sure if it was suspension or drive train.
