I got a 84 Pickup 4x4 with the 22R engine with 240,000 miles. Looks like I might be developing an oil leak, possibly a rear or front seal. Not sure yet, have to do a little detective work and find the leak. Got oil on the pan and can't locate the leak yet.
The big question is how hard is it to replace the rear seal and/or front seal?
Any information is greatly appreciated.
Front seal- $ Rear seal- $$$$$$$$$$$
Take a rag and a flashlight and check behind the front pulley. You can change the front one easily without much disassembly beyond the pulley. The rear will be a major PITA. You'll have to pull engine or tranny for that.
