  1. Suspension&Steering
    Hi all, I am a newbie here to the site and to the Duramax platform. I’m also sure this issue has been answered 1000 times. I recently purchased an 08 3500HD Duramax drw 135k miles.. Mainly to pull horse/livestock trailer and camper. Previous owner had the power steering pump and gear box...

    Lately on my truck the steering has felt off by a lot, whining, hard / stiff steering and gets worse as the truck warms up, I had even cleaned up everything within the engine bay too including the driver side intercooler pipe, which is now covered in a black grimey substance behind the ps...

    Newbie here, I have a '09 2500 LMM. This past week I have lost all power steering to the right, but not to the left. Turning the steering wheel to the left can be done with a finger, but as soon as you turn to the right it's a wrestling match if you're under 5mph. Power Steering pump has been...

    I have an issue with my 2005 2500HD Duramax where the power steering and brakes don't work for the first few seconds after starting the truck. After a few seconds they start to work normally. I have replaced the power steering pump, all power steering hoses, and the hydro boost unit in the...

    Hey guys so I just replaced my steering gearbox with a redhead one and replaced my burnt up ps pump and after that my power steering was great but my brakes were pretty bad still.. so I did some reading on the forums and decided to replace the hydroboost with the LML one. Just got it all back...

    2012 GMC 3500hd 6.6 LML I recently had to replace my steering gear box which was full of shredded metal. I replaced the gear box, power steering pump, cleaned all the lines, and replaced the hydro boost while I was in there. I’ve replaced and torn the whole system apart 3 times now due to back...
  7. 2001 - 2007 (GMT800) Non Powertrain
    Hey everyone, so I replace this hose about 3 years ago or so and now it's leaking again. I believe I bought the Edelman brand from RockAuto but I'm thinking of getting something better. What is everyone's thoughts on this part and brands to look at or ones to avoid? AC Delco is probably at the...

    New to this, but I’m a standstill.. had it looked at by a diesel mechanic and he said it’s the p/s pump, so here’s the problem when in the lower rpms driving or stopped if I press the brake or turn the wheels I get this bad grinding sound and a lot of vibration... the whole master cylinder...
  9. 01-04.5 LB7 Duramax Powertrain
    The title says it all, it's broken off 3 times and no one can tell me what's causing it. This last time it actually broke the center of the pulley out, right around the p.s. pump shaft... Has anyone had this issue? Is there a fix? Is there anything I can check out? None of the other pulleys...

    Hello, I need a schematic of the power steering system. I've got a leak on the part behind the brake reservoir. there are 2 high pressure lines and a return line going to it. It is leaking at the joint between this mystery part and the brake res. I believe it is a booster unit for the brake...
