I can't own a truck without bumpers, it's a must with my lack of paying attn and where I live. Stock bumpers are clean but look like shit when there's a deer or random object hanging out of them.
Power steering flush will help for a bit. I have to run a large cooler to save pumps.
I had a 6x10 cooler on the LLY after eating 5 pumps and the last one made it almost 100k when I flooded the truck.
I have a factory GM gasser cooler on the LMM and it doesn't help at all. Working on pump number 3 at 78k miles.
Does anyone that owns an LB7 have any prob with there power steering and brake booster? I did a search n seems like everyone had a lot of different opinions about what was causing it to whine n b extremely hard to turn at low speeds esp pulling a trailer.. I seen several said it was prob air in the system but I don't think that's the case on this truck.. It seems to do it worse when the truck has been drove 30 min or more.. Anybody got sum good info or tips to help me? The fluid is full in both. When u press the brakes to the floor the start growling like the ABS is kicking in but never had any prob stopping and it will only do it if I press them to the floor..
Get a boost valve, change fuel filters often , put a oil tap at the low part of oil pan. Mines on 336k and counting and pulling good on second set of injectors

I'd bet your power steering pump is about to go. They loose braking and steering power thousands of miles before it actually gives up and either starts eating belts or just plain old locks up. Mine would actually loose all power assist every once in a while before I figured it out.
How did you do the tap on the lower part of your pan?
It's going, mines doing it again. I have a spare in the garage, I had a feeling when I did the GM cooler it wasn't gonna be enough and I was right. I'm doing a larger cooler, junkyard steering box (mines leaking) and another pump next days off.
If you've got another good pump, replacing it would probably be a good idea. Only going to cost you time.
