91 is computer controlled for the trans but the engine is another issue. its been a few years but i know gm used basically a tcm that was pretty much a standalone computer as it would only receive signal from a few sensors on the engine as the 6.2 and think the 1992 6.5 didnt need a computer to run.

Yeah this is why I was wanting to go to the older 6.2 with the 400 turbo trans so the engine and trans is all mechanical and I take the computer(s) out of the loop.

I do know it has the OBD1 port on it. My 1990 burban had the same thing but it was gas and the 87 did not have an OBD1 port.

Got my CUCV bumpers and brush guard put on the Burban. I also mounted my hi-lift jack to the front.



I also put in a new dash cover, radio and new front seat. Next will be the 4” lift wheels and tires then off to paint.

Nice bumpers.
I'm a huge fan of CUCV's.
Do you plan to tow with that pintle hitch?  I'd check it out first.  Someone's done some custom work to that hitch.  That's not the factory set up.

Oh yeah I double checked it. The receiver hitch was on the Burban when I bought it. I had it off when I was installing the rear bumper and inspected all the welds. It’s really beefed up. I was going to put the old receiver hitch off my K5 I sold but I likes this one better.

Put the roof rack on this weekend. She’s coming along. I guess the lift will be next.

Of course! I wanted to fit and measure everything, drill my holes and mount it. Now when it goes into paint it will take me about 30 minutes to an hour to disassemble and about the same to mount it back on when she comes back from paint. If I would have tried to do this after paint I would have had scratches everywhere.

I have a new issue that has started; since I’ve had the truck she has just floated down the road like a caddy. Yesterday out of the blue she started bouncing/vibrating at 40mph and up. It may be at lower speeds but I can’t tell. I thought maybe one of the wheels lost a weight and was out of balance but everything looks in place.

Any ideas as to what it might be or what I can check next?

Does it currently run OK right now? If yes, why not wait till there is a problem to make changes?

Dana 60/44 death wobble. Do a search for it. Probably need new kingpins. Very common.

Yes, she runs like a champ! Not sure why I should wait until there’s a problem to make changes? There is a problem; she went from driving like a Cadillac to driving like a dump truck. I’m not going to wait until the wheels fall off to fix it. I’m trying to stay out in front of the issue. I learned a long time ago that the longer you wait to address an issue, the more it’s going to cost to fix.
