No more replacement of shafts, must lubricate. Once stock runs out on these, we have to go through a lot of hoops to get a replacement one. So just a heads up, wont be the dealer trying to blow you off if you need a shaft.

GM's trying to cut cost anywhere/everywhere they can...now we have to pay for their bad design??? How long before they recind the injector warantty?
Glad I just got my shaft done before they changed this. I went in and asked for the grease kit and they took the truck right in a changed the shaft. No charge and no argument at all. But, I live in a one traffic light, blink your eyes and miss it, type of town and they have a limilted customer base (all locals). Perhaps they can't afford to shoot themselves in the foot.

High Pitched Whistle Noise on Turns with 700 Series Gearbox - keywords hose left right steer steering valve #PIT3482A - (Apr 15, 2005)
High Pitched Whistle Noise on Turns with 700 Series Gearbox
2003-2005 Chevrolet 2500/3500 Silverado

2003-2005 Chevrolet Suburban

2003-2005 GMC 2500/3500 Sierra

2003-2005 GMC Yukon XL

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in the PI.

Condition/Concern:
Owners may comment of a high pitched whistle noise coming from the steering gear while turning. An offset drilled oil return hole in spool valve has been found to be the source of the noise. The whistle noise is mainly on left hand turns. This only applies to the 700 series gear box.

Note: To properly identify a 700 gearbox, the stubshaft is held in place by a threaded retainer and lock nut, SI Document # ID 1551804. A 680 gearbox uses a stubshaft housing that is attached with 4 mounting bolts, SI Document # ID 725682. A 670 gearbox also uses a stubshaft housing but is only retained by 3 mounting bolts, SI Document # ID 415118.

Recommendation/Instructions:
To correct this concern, install a power steering adapter (P/N 26109078) between the power steering gear and the high pressure hose.

If the noise is not corrected by installing the adapter, replace the steering gear with a new gear for GM SPO parts. Current SPO parts contain known good stock.

All models listed built after January 14, 2005 have the revised steering gear box

Please follow this diagnosis process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.



GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.

My question is, how is just grease going to fix this??? I have been a mechanic for a very long time and in my experience if something needs grease and dosn't get it in a timly manner it gets ruined...I have changed a ton of bearings that have had this problem...no grease and continued use.

This is speculation on my part, but the grease they have been using is not thick enough for the clearance spec. The "clunk" is not a bearing, but the splines of the slip section. There is no danger to this part, just really freaking annoying.

I hate to ask this because the topic has been around the world, but ......
I picked up a new intermed steering shaft yesterday (new design supposedly) and will install this weekend myself. Do I need to use a grease pack on the front end, or just expect to do that in approx. 20K miles? Yes, I'm pessimistic about this GM shaft being any better than the first one. sorry.

Thanks Catch. I'm going to proceed with installing the new one since the original was repacked twice and now with 79K miles the service tech suggested trying the new shaft. It wasn't but $100 so if it only lasts 25K miles before needing a greese pack, I can say I tried! Maybe I'll get lucky and this will fix it for good.

Let me tell you guys you can buy the lube kit but you will not be happy with the long term results. I bought one, removed the shaft, disassembled and cleaned it. It was evident that there was not near enough grease. I took the kit back and packed mine full of Mobil 1. Not a clunk in a year and a half. If it comes back I am going to look at installing a zerk fitting. Later! Frank

what about using some heavy duty wheel bearing grease or trailer bearing grease?

I packed my '02 with the "fix kit" grease and it did not seem to do much

Remember the shafts in the "800" series trucks? Tight fit, coud barely slide them sometimes, solid lower shaft fitting into upper tube. New series, loose fitting splined assembly, easy to slide.... the looseness is the noise in the shaft, IMO not a safety issue but only an annoyance... mine has made noise from day 1 but I ignore it.

Mine had the clunk since 20,000 mi, had it fixed/greased at the dealer, came back a few months later 48,000 on it now it seems to be getting louder. I'll do the grease kit if the dealer won't change the shaft.

No problems with this truck yet, but it seems GM has had the steering shaft problem for years. I had a 99 Z71 and had it fixed two times and it needed it again when i traded for the 02 Z71. Had the 02 fixed two times before trading it for an 03 Avalanche. The Avalanche needed a fix when i traded it late last year. But i can say that is the only problem i had with any of the trucks.
