My 07 NBS had a trans or AC line rubbing on the power steering pump resevior (SP). I m sure after 20,000 miles or so it may have been a problem. It is a metal line so I bent it slightly away from the resevior to avoid any future problems. Check yours to make sure that wasn t a problem with all of new 07 s..

When I bought my '05 Grand Prix GXP, I had to bring it back the next day with the block heater cord burning off on the rear exhaust manifold. A quick check of the others on the lot found them all with the cord in the same place! I guess stuff gets missed at the factory sometimes. :cheers:

All NBS truck and most 06 classic trucks have the same problem. Oddly enough that this came up, i put a suggestion in at work to have a spacer put in on the line to prevent premature wear and recalls. So far, nothing. If they use it, i get up to 25K as a reward.

 

Lets hope!, the Camaro wants more toys!

On these trucks...the trans cooler lines are on the PASSENGER side of the vehicle.

The power steering pump / resovoir is on the DRIVER side...

 

Explain to me more of what you see.

Out of curiosity, I just went outside and crawled around underneath my 2006 Sierra to check out this story.

1. Trans lines are secured in their clips...and are nowhere near anything.

2. All A/C lines are correctly routed...and are nowhere near anything.

3. Nothing out of place near the power steering system.

It's not the trans or Ac lines, its the power steering lines coming from the rear of the pump down to the rack. One line on some 2005/2006 models have this problem, mine does, all 07's have this problem, look on the drivers side, if yours does not have this problem, dont worry too much about it.

So, you must be talking about 1999-2007 OBS 2 wheel drive trucks, or NBS 2007 models, right??

 

Because 4x4 99-07 OBS trucks DO NOT have rack and pinion steering; they have recirculating ball steering.

I noticed the same problem with mine. Take a closer look, it's the hydraulic line from the back side of the pump to the steering rack. On mine, there is too much pressure to simply pull it away. This will definately wear a hole in either the line or the pump resevior if left alone.

 

I stopped by the dealer so they could look at it and order parts if needed. They decided to not mess with it until they can remove the line and adjust with a tubing bender. Almost due for its first oil change, said they will fix it at that time.

Here's a pic of the Power Steering (P/S) Pump on my 2007 GMC Sierra (NBS) 6.0L.

Is this where everyone is talking about the P/S line rubbing on the P/S Pump, :banghead:

picture is worth a 1000 words.

 

P/S Line was lightly touching the pump, I carefully pulled the line away so it just clears the pump now!

Yep, that's the spot. Only mine is so tight there that I can't even budge the line away from the resevior. I wonder if the line is loosten if there is any rotational play to give some clearance?

Thanks for the pic BRT. Mine was snug against the pump, just had to pull it away a little.

      Acceptably cheap tires?

      By Atlas · Posted

      Which one, the AT or AS?   Starfire is made by Cooper/Goodyear but at $85/tire I'd think I'd need to level-set my expectations that they may not even be round 😉 But you're saying they're decent?   I'm already into this thing $1506 in parts, fluids, etc. Totaled all my receipts today. $250 of that was replacing an EGR and MAP sensor that were probably fine, but I'm not going to return the parts since they've been installed. I'm cheap, but not that cheap. I use it, I keep it!   I may or may not make money if I sell the truck at this point, but, that wasn't really the point. And if I billed my time, I'd be hosed for real. My thought on the tires is I "might" put 1,000 miles on before selling it. I just don't want to put absolute junk on it, that doesn't do anyone any good. If the Solus solidly isn't junk, I'll definitely consider them.

      Is your l8t engine bay super dusty?

      By rjgvt · Posted

      I leave mine as is. I'm always a trip away from riding on unpaved roads. Dealer can clean it when they prep it after I trade it in for another new truck.

      I have these on two vehicles and love them. Pepper is one of them 😉

      4WD. Far as I know it came stock with P's and not LT's. Definitely planning to put P's on it, but stock is a 109 XL load rating so I should probably stick within that guideline.   No rebates on anything I can see at the moment. Discount Tire is offering $50 off, but Pep Boys is very competitive on price, and also carries all the off-brand stuff. Les Schwab always wants an arm/leg, but they do good work.   It still has the original spare. Goodyear Wrangler RT/S, thing looks like a tractor tire LOL!! How times have changed.

      2020 Sierra 2500 windows rolling down

      By JohnRoy · Posted

      2020 Sierra 2500 HD (base model) gas engine 4wd.    All 4 windows roll down on their own. Happens somewhat randomly after stop and engine off - when engine turned off, when walking away from vehicle before or after locks activated. Pulled the window fuse F14 Instrument Panel Fuse Block Right; the driver's side still activates from driver's side door panel; passenger and back seat windows activate from local switches on their doors but not from driver's side group of switches. Power mirrors don't activate with fuse removed either (same fuse for both circuits). Problem not solved.    How can they even activate with fuse removed but they are all still opening and can control from each door?  When they open on their own, I can shut them from the switch in each door, but they don't stay closed.    Seems to be activated somehow with key fob; something bumping the key fob in my pocket or just handling - removed key fob and took it far enough away and now the windows stay closed. Replaced key fob batty just in case, no change.    Sounds like some kind of wiring short or maybe electronics. Dealer will first replace electronic control module without checking anything else and I anticipate problem will still exist since their troubleshooting skills are limited to "do whatever the computer says".  In any case, keyfob seems to be activating the circuitry.    Surely I'm not the only one with this issue, but I can't find anything related on the site. What do yall think?   JohnRoy
