    Steering box input shaft second seal/dust seal?

    Need some help on identifying if I'm nuts or not. Just rebuilt my steering box on my 2003 2500HD, screw cover that torques down the valve assy is my question area. I did another truck about 3 years ago and was fairly certain there was a seal in this part in addition to the input shaft seal...

    2003 C4 Connector pin-out? (front light harness)

    I went through the TSB forum LB7 and LBZ sections. I was able to find the C4 connector pin-out for the LBZ, but can't for the LB7. This is the green plug that goes into the underhood fuse box and goes out to the headlights/DRL, turns, fogs, horns, etc.. In short, trying to chase down a DRL...

    Question: 2011+ hub/bearing/brake swap to pre 2010

    Ok, I'm very comfortable with modifying and custom fittings/grinding/etc..., and before I go buying parts to start down this road, I'd like to see what I'm missing. Truck in question is a 2003 2500HD 4wd. Lowered all around, spindles and keys, shackles and relocated front leaf mount. About a...

    Can you install the 07.5-10 steering box in a 00-06?

    Searched all over and can't find any info on this. Just as the title says - GM changed the steering gear box on the 07.5s and I understand the frame stayed basically the same till 2010. So I have to replace my steering box and have a good line on a low mileage OEM 2009 box - can I use it...

    LBZ: Min pressure ECM needs to fire injectors on start?

    So, I'm troubleshooting a crank/no start condition on my recent LBZ swap. Everything appears to check out, and I wanted to see if anyone has the actual pressure the ECM wants to see on cranking before it will fire the injectors? I see 6-7mPA when cranking - so a little over 1000psi. I've...

    Crank, no start LBZ swap

    Well, running into a wall and looking for some collective help. Everything is swapped on my 03 from the previously swapped LLY to a full LBZ. I do have a MATCO MaxMe scan tool which gives me just about all the Tech II functionality, but not 100%. Here is what I have: Wiring verified...

    03 built 5 speed conversion to a 6 speed via OEM?

    I know some of you will read the title and think you know what I'm asking, but I'm not asking how to put a 6 speed behind my LLY. I'm swapping my LLY out for a LBZ and I have a stage 5 Suncoast built 5 speed trans that works great. The trans I'll be getting with the motor/swap was a flood...

    Allison 5sp: Used trans value?

    I searched but didn't see any older threads and was looking for some advice. I'm selling my old '03 Allison and I'm not sure what the used values are right now. I checked on local craigslist and the 4wd models seem to go for $1000-1500, but I've had mine for sale for a few weeks now with no...
