What did you do to your NNBS GMT900 Tahoe/Yukon Today?

[89Suburban]

usually takes me at least 3 qt's for it to start coming out clean looking

I’ve only done it once, it took over 3 quarts like you before it looked nice n clean.

What is the process for this?

I think that was the powersteering fluid flush.

I went through a good 4 quarts before mine looked good.
After driving for a while, it needs to be done again.

Lots of sludge in my pump, part of why I'm adding a filter adapter for the return line.

ETA: I read that wrong, see what Rocket Man said below.

I made a little hose extension to get the hose out of my wheel well
Do it with the engine off.

What is the process for this?

I disconnected the return line at the power steering pump and used a rubber cap to plug the nipple on the pump, then used a barb to connect a long hose (5/16” or 3/8”?) to the rubber return line and put it in a bucket. Then with the front on jack stands, I turned the wheels from lock to lock without starting the engine. Keep topping the reservoir, make sure to not let it run dry and get air in the system. Keep doing it until the fluid runs clear. Some videos I’ve seen show them starting the engine but I don’t think it’s necessary and requires 2 people.

Don’t remove the high pressure line or you’re f*cked lol. That’s the one with a fitting you have to unscrew.

when I did mine I just lifted the front until the wheels are off the ground, extracted the fluid from the reservoir, refilled it, put the cap on and started the engine and turned the wheels to full lock back n forth several times and repeated until I had gone thru all the fresh fluid

DOH, I thought he was asking how much does the power steering system hold!

You guys actually disconnecting the line and draining it then refilling, or just sucking the reservoir out and refilling/drive a bit/repeat?

EDIT: DOH, I see you explained your procedure in a later post, lol

Not today but did do both hubs actually not that bad of cost. The stock ones did there job and lasted 160k + haven't given her a burst of highway to see if fixed my issues.

What brand did you go with? As you noted, OEM hubs usually last 150k or more. Timken are what most of us use, they make a some of the OEM hubs on our trucks. Detroit Axle has a bad rep, there’s been catastrophic failures and there’s no telling how long they’ll last.

Oem Ac Delcos. I know Timken weren't a bad option either. but yeah, I heard Detroit axle aren't very good.

Used Moog hubs when I just replaced mine, along with their upper control arms

I like Timken and SKF.
