Hi,

New owner here from Western NC. 1973 C10 Longbed, 350 TH350. Father son combo, weekend wrenchers. Bad dealer experience, transmission rebuild after only 300 miles ($$$). Zero play in driveshaft hammered the transmission to bits. Lesson learned. Happy to be here!

Hi all, I am new to the forum.  It’s rare for me to feel the need to make any posts about questions since everything has been discussed at length usually, especially pinion angles.  My issue seems to be odd which is why I’m looking for some help.

My truck (1978 k10 long bed) has what I believe is a 4” suspension lift (no blocks, full leaf lift) and 3” body lift.  The issue I’m having is that I believe my truck has a pinion angle that is pointed too high leading to vibration issues.  From what I gather, most people don’t need angle blocks with a lift on long beds and if they do need them they are installed to point the pinion higher toward the transfer case.  In order for my transfer case and my pinion to be closer matching in angles I would need to install angle blocks backwards to point in down some.

My measurements below were pulled using the Tremec driveline angle finder.
Transfer case: 2.2 degrees
Driveshaft: 13.2 degrees
Rear pinion: 9.9 degrees


Am I correct in thinking I need to install angle blocks backwards to try and get my pinion angle closer matching to the transfer case?  Or would this be a candidate to drop the tcase to lessen the difference between the tcase and driveshaft?  Either way, I think something is wrong here and is likely causing my highway vibration issue

Thanks everyone

Hello I have a 1986 k10 my vss has two connectors on the opposite side of the wires going to the speedometer one connector has three wires and the other has one wire. My question is where the one wire connector goes to ?

My left rear has a wobble, makes for miserable driving. Steel Rally 6 lug.

There is a place locally who's website says they straighten them, but they can't seem to get their story straight so I've lost trust and am moving on.

Would like to keep the stock look, as tempting as new wheels are.

Here is the stamp near the air jack, it's 15" in diameter, does the '11' indicate the bead width?

Anyone have some they would like to sell? Or sources?

Thanks in advance for your help!
