1989 GMC Suburban "Trail Boss" conversion

I am guessing it is running worse without the running boards?

I thought it was red tow hooks what made a 4x4 run better.

I thought it was red tow hooks what made a 4x4 run better.

Probably would if they replaced chrome tow hooks.

Recently re-watched Dante's Peak. Kind of a sucky movie despite James Bond and Sarah Connors being in it, but great trucks in that movie

Awesome build, love an old square body. Keep fighting the good fight on the engine woes,
problems like those are less than enjoyable until they are solved.

pulled the transfer case over the last couple evenings, I kind of expected to see more of a sign of fluid in between the case and adapter considering there was about a gallon of trans fluid in the transfer case. I didnt see any visible damage to the seal but the rubber was pretty hard. Picked up the needed seals last night, going to replace the input and both outputs since its out.

Cleaned about 10 pounds of grease, oil, dirt, and mud off the transfer case and the skid plate. Changed out the input and both output seals and got it reinstalled.

The driver window has not worked since I bought the suburban, I put a new window switch in (as it was hanging from the door) but it didnt fix the window. I bought a new motor a while back and finally got around to installing it tonight. Did some testing first, pulled the window switch and tested the wires at the switch to make sure power was going out, pulled the motor and regulator, with the motor in my hand and hitting the switch i could feel it click but no movement. I had planned on adding relays to the window motors to speed them up but this new one moves pretty quickly and i didnt even grease the track. Now I need to order two more for the passenger side as they are really slow.

Yesterday was my birthday and I got exactly what I was wanting... time to work on the suburban.

Changed the oil for the first time since owning it (not that I've put that many miles on it)
Changed the trans filter and pan, the old pan was leaking around the gasket from being over tightened before

this little bastard was a pain to get out

The fill plug on the rear axle had been rounded out so I welded a bolt to it... and broke the bolt

So I welded a castle nut to what was now sticking out and was able to get it out, surprisingly the rear diff wasn't that low

The new front output shaft seal on the transfer case had already started leaking after a 2 mile drive so I pulled the seal and got another new one to put it. The design has has been updated from the old one and I put it in flush with the case but I think it needed to be seated in further. If it starts to leak again I know I can order the old style online.

Then drove the suburban into town for some fresh gas and wash the windows lol.

The second front output shaft seal is leaking again, this time it took about 20 miles to start instead of 2. when looking up the seal all the auto part stores update to a dual lip seal

I found this original part number one from Global Transmission, so after I get back from taking the scouts to summer camp, I get to pull the front driveline AGAIN
