I may have missed this in the write up. Do you know there is a centering pin/bolt in the leaf springs to keep them centered and not fanning out and back and forth. Just tightening the U bolts is not going to make the springs stay together and centered. Actually the U bolts are probably over...

Have you had the front end alignment checked on a machine that has a qualified operator? No tape measure alignment and guessing. These issues are hard to resolve with things being misaligned, out of round or unbalanced tires. Adding a lift kit and other questionable suspension modifications just...

I am referring to the outer axle U joints. They can become tight and not return to the straight-ahead neutral position on one side and make all sorts of things happen. I had them front axle U joints bad on a 1984 M1028 and the 1984 M1028 had a different rear cab crossmember. It had just cab...

Did you check the outer axle U joints? Is one of them bound up. I had it happen several times. Good Luck.

OK. You ask for my opinion. I was a GM Service technician back in the late 70's and early 80's. I was not the transmission guy. The dealership I worked in we had guys that did transmissions and we had guys like me that did general service work, warranty and factory recalls. I did Pennsylvania...

I had an M1028 A1 that had indecisive shifting. I changed the VRV and that made no difference. I took it to the transmission shop, and they adjusted it with a gauge. He said he was not happy with the way it shifted either. As time went on it remained a PITA. It would pull out in 2nd and shift on...

A rebuilt transmission does wonders also. I had one that was indecisive and shifted erratically. I dropped it off at the transmission shop of a friends and he called and said it was pump pressure, burnt clutches or some other failure inside. I was doubtful because the vehicle had 19 K miles on...

As an extra measure disconnect the hose from the vacuum pump and start the engine. It should suck your fingertip fast to the connection at the pump while idling. Or at least make a chirping noise that indicates it is creating a vacuum. Good Luck. Report back and Merry Christmas to all and to all...

Before you do any of this make sure the vacuum hose is still hooked up to the vacuum pump on the rear of the engine. Make sure the hose is not cracked and broken open or sucked shut. Also check the white plastic hose adapters that take the hose from 3/8" to 1/4" I have seen a fair share of them...

I have had the misfortune of changing starters, transmission cooler lines, U joints and drive shafts out in the frozen tundra while laying on my back on the polar ice cap. It happens. It needs to be fixed and the faster you just apply yourself the faster it gets done. I would recommend anyone...

I said this before. If you have the starter out and you know nothing about how long it has been on the job. take it to a professional rebuilder. I never wait for complete failure of anything. most times it is going to fail in the farthest and most in opportune time that can be imagined. I always...

No gasket. Just take your time and put everything back the way it belongs. No short cuts or half fast tricks. Good Luck. I will be here waiting for a report. Have a question? Please ask no question is bad except the ones you don't ask and break something. Doing it right the first time is the...

The OEM 6.2 diesels and gas engines were SAE standard all the way up to the old cab V/R cab chassis, Suburban and K5 Jimmy and Blazer models. GM used standard body bolts and metric and standard power train bolts all the way up to the new 1988 cab. That was a very confusing era when it came to...

No, I am sorry. The bolts that bolt a bellhousing to the block of the stock 6.2 are 3/8 - 16 SAE. That may not be the case on that fancy new engine you have but I am 100% positive I have used a 9/16" swivel impact socket since the 70's to remove any transmissions in GM truck up to the 1991 R & V...

I think you are ready to go. I completed this job on a lift and on the ground. Either way you don't need to remove the transmission to do the job. Just 4" long 3/8" bolts and slide it all back and replace everything. I changed over a 100 of them. The hardest part I encountered over the years was...
