This is my first post here on JeepForum. I just picked up my first Jeep a 1993 Grand Wagoneer w/5.2 and quadratrac. It needs exhaust and both tail lights are missing. I loved the thing from the test ride. Turns out the truck is an Arizona native! Little rust, just on the front passenger side door. Took it down some mild trails nearby and was thoroughly impressed. I paid the guy $500.00 started driving home but never made it. About a mile from home I started to smell oil burning so I began to pull over when the front end made a noise and I felt a learch. I go out and looked at the front axle assuming it was a toasted caliper or something. I noticed diff fluid squirting out of the pinion seal and the diff housing was steaming hot! My old man was following me so I told him I was just going to drive it home as is. I started to pull out and my dad was yelling "It's on fire !!". I got out and looked and the pinion area was on fire ! Thinking quick I jumped in and ran the jeep into a mud puddle on the self-storage parking lot I pulled into. That put the fire out for a few seconds. While I was standing there looking at it, the fire started back up! I knew there was a jug of anti-freeze/coolant in the back seat so I pulled it out and doused the diff a few times. The fire was pretty minor and didn't damage anything. I took my wife and dad to dinner to let the truck cool down. I went back and drove it home from there. The front axle made groaning and grinding noises all the way. I knew the front axle was toast. So now the plan is to tear out the front axle and replace it complete. Anything to watch for? So far I gather that the front pinion bearings have a habit of grenading randomly in the ZJ. I don't know my gear ratio yet, I have to crawl under there and get a good look. I'm assuming 3.73s, it has a hitch and tow package ZJs had 3.73s and it felt well geared when I drove it. No idea yet though. Anybody know if the Wagoneer had a specific ratio? My dad's friend owes him a favor and this favor owing friend just happens to own a salvage yard so I have the ability to get an axle free.
My queston is are there any known problems to look out for other than pinion play ?
How about getting the axle out?
Jack up the truck by the axle
Set the jackstands under Lower Control Arm mounts
Let front axle droop
Remove Drive shaft
Remove calipers and zip tie up out of the way
Remove tie rods
Remove anti-sway bar links
Remove track bar
Remove upper then lower control arms
Pull axle out from under
Install new axle in reverse
Missing anything ?
Are any of the nuts/bolt problematic?
Any special tools other than a tie rod remover?
Thanks in advance guys, this is my first jeep and I hope to be all together and running with a set of 31's for the Jeep Jamboree in Mole Lake this year !!
