Yikes - a knock after replacing the tensioner. So much for the easy fix...
If you have 4WD the oil pan is almost impossible to get off without removing the crossmember, flywheel cover, the starter, front axle, part of the steering assembly and the front tire.
I hope you have 2WD!! If you do, only some of that stuff has to get taken out of the way.
But it ain't like some engines where an oil pan is fairly unobstructed. Plan on a lengthy process to check those bearings.
Wish someone would develop a mechanic's endoscopy probe small enough to snake down the oil fill tube and be used while the engines running. Heck, if doctor's can peek into a beating heart and measure molecular plaque, why can't someone make a crankcase tool to check clearances? What's more important anyway?
