Help - Power steering non existant when braking hard

[LagunaH1]

Yikes, sorry to hear about such bad luck

I anticipated a few replacments would occur as the previous owner abused the hummer a bit from what I gathered from the vehicle history. Just glad everything is happening at once. Warrenty claim on power steering was approved and then the wrong pump was ordered, awaiting correct pump delivery, should have the H3 back on Saturday

So I fetched the Hummer on saturday, new power steering pump and gearbox. The H is running smoother than when I bought her, but now i can actually feel on the steering wheel when the steering column is rubbing against the headers. this weekend we are doing a mild trail up near Hartebeespoort, and will be using a fellow H3 owners go pro camera to look under the hood and see what exactly is flexing when the rubbing occurs. engine and gearbox mounts or steering shaft.... so who wants to take a guess as to what the real culprit is :huh:

No guesses, but good luck. Glad to hear about the trans fix

Did the trail this weekend. Hummer performed flawless. Untill we took the dirt road out, and on a tight right turn. Carnage, sounded like metal on metal scraping. but with a rubber undertone. hard to explain. in short the front left cv had gone. I drove it to destruction. Whats pyzzling me is that there,s aonly a slight tear in the cv boot on shaft side, and the clamp thats supposed to be there is running loose on the shaft with a cable tie holding the cv boot in place on the shaft. and also with the boot torn you would excpect massive ghrees coverage of all components and even inner rip, but nada making me think i bought the hummer like this 6,000km ago.

Wow, So what? You where driving in 3 wheel drive all this time???
I don't think the boot is strong enough to hold the shaft in place for so long.

And finally the Hummer is fixed (according to GM anyway's) fetching her on Satruday, and then I will do some testing to make sure. Power steering pump was the prolem for the no steering when braking, and the rubbing on the steering shaft, was due to the steering shafl not propperly bolted to the stering rack, thus fastening and loosening as you apply force on the steering wheel. Pretty nasty if you think about what could happen if the steering column came loose at speed :no:

......, but now i can actually feel on the steering wheel when the steering column is rubbing against the headers.

where did you get your headers?

 

[ArtHummer]

No steering when braking going down the hill and loosening of the steering shaft... this sounds like a recipe for desiter...
It is good that they figured it out sooner then later.
Good luck to you and your truck.

where did you get your headers?

Found it at a local South African exhaust performance shop. got the long headers to retain the low down torque, plus had them powder coated to get some heat out of the engine bay. also did dual free flow 63mm. total cost ~ R12,500 ($ 1,260)

Believe me thats an experience nobody wants to have. luckilly I have a code 14 licence (allowed to drive big rigs with abnormal loads etc.) so I just used that training, lower gear and engine breaking down hills. If I had to I would have used 4lo as a last resort :huh:. And I have learned the hard way check check and recheck everything yourself, dont assume the dealership/workshop has checked everything you asked for.
