Bought me a Mall Crawler Today

Nice burb! My father in law has a 99 K2500 with a 7.4, up over 200,000 miles and no issues yet with it, and it spent a lot of those miles pulling a 3 horse trailer through Colorado mountain passes. Finding one with 64,000 miles is a score!
 
My wheelers short block is a l29. Had a 100k and no noticeable bore taper.

Same story here for my dads. Except for the hauling part.
 
Thanks Mr Helper.
His truck is from the old days...which is what I was referring to


You bet, always glad to help :waytogo: 1999 is not the old days. The September cut off for new model year vehicles hasn’t been accurate since the late 80’s. Only Autozone’s finest still believe anything built after September is the next year model. While that may be true on some cars, it is not true for the majority of vehicles. GM is building 2014 Impalas right now with 2014 model year VIN’s and it isn’t even September yet :whistle:. Manufacturers have been playing the model year game for decades like that...

My point is don't go by the month and year a vehicle was built. Go by the year digit in the 10th position of the VIN.
 
Are those Rancho upper control arms?
Is the subframe a bolt together multi-piece unit or one solid subframe?

Reason I ask is the red upper control arms make me suspicious that's the old Rancho lift kit from the early 90's. Had lots of weird geometry issues and wore out steering and tires bad.
They pioneered the one piece subframe kit after that debacle.
 
Looks really clean! Definitely a 7.4L Vortec. That 454 is a solid motor. I owned 2 of those trucks, and they were both a lot faster than a truck that size should ever be.

If you happened to have a multi -piece rancho front subframe, you can get it properly aligned, and get someone to weld it solid.

Good looking rig!

The problem was more with the upper control arms. Their geometry was off and the diff wasn't dropped enough.

Ah. Oh well. I'd guess a 96 and newer truck would have the good one.

Alignment and tire wear will tell the story.

Sweet truck, either way. :waytogo:

I'm jealous. I sold the clean Late 90's burb i had, and the recent one i bought was a POS.

Love that body style.

Throw a set of the newer towing mirrors on that beast, they compliment the stance and body of these rigs well.
 
The red upper control arms are what caught my attention. The good later lift just used the factory arms.

I just had tires balanced & aligned yesterday. What am I looking for multi-piece wise and what would I weld.

Is there something I should be looking for or at on that upper control arm.

This is all new to me so I don't really know what I'm looking at. Tires seem to have normal even wear. all ball joints and tie rod ends seem fine. It does thou at about 35-40MPH have this wheel wobble but goes away over 40 and rolls just fine at freeway speeds. The wobble shows up both acceleration and deceleration at about same speeds
