Here is the original thread....

My dilemma is order part# 25900714
But it showed up and stated plainly it is lower sector steering shaft.

Is there only one steering component?
Gf's h3 was diagnosed as steering shaft replacement upper needed.

My fault.... I should of research any information or numbers more thoroughly.

Please help.

Do we have the right part or do we need to spend money again to purchase the upper and I'll just do both.
still cheaper than mechanic doing it.

That's the only part I'm aware of that could be a problem. It is #25900714 (part #26) shown here...

It is also the part shown in my photo on the original thread.

If you need what you are calling the "upper" shaft, its probably #19256702 (part #23) shown here...

This shaft comes out with column assembly (everything in shaded area #1) when you pull it out thru the cabin. I've had to remove a column once to replace the wheel position sensor, which is mounted right where these mate. Which brings me to my next point...if you disconnect any part of the steering, MAKE SURE YOU USE THE GM COLUMN LOCK PIN TOOL to keep the steering shaft from turning while working on it. Failure to do so will destroy the smart switch assembly, and can also cause the wheel position sensor to become mis-indexed when you re-install the column. There is nothing complicated about the H3 steering column but, you must absolutely keep it from rotating while its disconnected. Diagram below...

Lower/intermediate... it's the same thing. Are you sure they said upper shaft? The intermediate shaft is the most common cause of the clunk/noise in steering.

Lol guys were basing this off gf's memory of a year + ago. She can't remember what tech told her. Hahaha.
Hey I to can't remember stuff at times.

Well spent several hours and got the lower intermediate shaft out (talk about rust) it was a b@tch working in tight spacing but it is back together. Now the sad part it didn't fix the clunk.
I'm going to look under interior column next. First...
What is the inside upper shaft and mount assembly like?
Does the steering wheel have to be removed?
Gf's is kinda p@ssed...
She is tight for cash this month.

Did you check out the steering rack, tie rods and bushings while you were in replacing the shaft. These are all common wear items. Any noises can easily travel up the column and sound/feel like the Column itself.

All good points but I suspect it is coming from the steering. Checked the steering rack and other associated parts all seemed tight.
Ordered the part # 4speed referenced above.
Tsb we found talks about changing as a set as both can go bad.

Tsb we found talks about changing as a set as both can go bad.

What TSB number that mentioned replacing both shafts? Only TSB I know of is 07-02-35-006E which only calls for the intermediate (lower) shaft replacement. I'm really curios to see what you find as I'm in the exact same boat. Symptoms are dead on, but replacing the shaft didn't cure it. Keep us posted.

The shaft is a very common cause of noise steering.
