So you do have to remove the column? How else would you get that stuff off of there?

Yes the whole column is coming out.

After you get all of the kick panels out of the way this isn't all that hard of a job. The column is held in with 4 13mm bolts and a pinch bolt at the bottom... Down by the sensor. The pinch bolt is the bear... In cold weather you will need to heat the vinyl boot with a hair dryer or you'll never get it out of the way.

Tell me about it. I still have a hole in my garage wall from hurling a BFS out of frustration while trying to get the pinch bolt back in. Actually it was that experience that caused me to fork over the cash to the dealer when the SWPS went bad rather than go through that again.

Jim, you do mighty fine work and have some interesting cars, I really like the Jimmy. I had a 1984 and just loved it, bought a 2000 Blazer bigest piece of crap I have owned to date. Would love to find a jimmy like you had, are they out there and if so are they big bucks/

You dont have to but way easier if you take it out.....not that bad but you need a another guy, I put the seat all the way down and lay down with my head underneath the column. release everything and have my apprentice pull it out without turning the wheel. so ya as ol Jimmy said hire it out just make sure they can do it and have done it before hate to have yours the test subject lol......

They are very rare but I wouldn't say big bucks. You could only get them in 1992 and 1993. You can find out all about them at www.syty.org. That's the Syclone/Typhoon website. Mine was a Typhoon, which is the Jimmy-based version. I swear the AWD coupled with the 4.3L turbo would produce enough g-force to make you dizzy when you launch from a stoplight. Sometimes I wish I had kept it, other times I'm reminded of how tempermental it was. Definitely a fun toy, but not as a daily driver.

Cad Tech thanks for the detailed picture so I know what to check for loose connection. Will unplug and replug it in tomorrow and post if I get the code again.

Jim, checked out the web site, Thanks

Droved to store and Service Stability System code came up, went home played with connector drove two feet Service Stability System code came up again. Looks like I do need a new module, will probably wait to summer, but in the mean time will have steering wheel shaft check for service bulletin and if it is bad have both done at same time.
Thanks again for eveyone's input.

What makes you think it is the module... 9 times out of 10 it is the Steering Sensor.

goldwing1989 · #26 (**permalink**) 01-21-07, 08:35 AM

Sorry I did mean the steering sensor, I just could not think of the real name so I said module, thought I could wing it and forgot most of you guys do know your stuff.

I am getting Service Stability System message, and when braking i am getting a very strange feeling in the pedal.

Would a bad SWPS cause problems to brakes, aside from a strange feeling while braking, ie ruin pads or warp rotors??

Also I have been looking to find instructions to remove the steering column to get at the SWPS and the bearing. I know there are 4 bolts, and one pinch bolt which attaches to the intermediate steering shaft. But I have a few questions...

Should I disable the SIR befor i attempt this?

Once my helper pulls the column out, making sure the wheel stays straight, what do we do with it from there, just lay it down on a flat surface and go to work?

I also read in one thread that there is a SWPS retainer, p/n 07847029. The only replacement parts I have are the bearing, SWPS and intermediate steering shaft. Do I need to get this retainer or can I use the old one? Has it been redesigned? I only found out about the retainer this evening.

Thanks!

I am having the same issue and need to get the parts together for this. Please let me know what I need.

GeorgeJung · #29 (**permalink**) 08-14-08, 08:58 PM

From what I have gathered you need the Steering Wheel Position sensor, the new intermediate steering shaft, and the new (orange) intermediate shaft bearing. Beyond that I do not know.

HELP!!!

iametarq · #30 (**permalink**) 08-14-08, 10:07 PM

I would get all new parts for the intermediate shaft. i need to replace mine but I am going to have a professional do it, I don't believe I have the skills to do that work.

If you do it yourself, to answer your question, I would disable the SIR by pulling the fuse...and then the Neg battery cable just to be double safe.

but that is just me...
