I unbolted the steering shaft coupling but can't get the dang thing to slide down and seperate so that I can get the EVO Sensor off! What the heck am I missing? Anything tricks to this? Here is a where I got the instructions... FSC I would have replied to that thread but the DA's moderating over there won't activate my Username for some reason despite my repeated email rants. Hopefully I can get some help over here. Thanks

Whats an EVO sensor? Must be one of those new fangled things...
I pulled off a shaft today, I undid it at the top part first and then did it at the steering box too, took some wiggling but it came off with some work.

EVO stands for "Electronic Variable Orfice"... On 97 and later GM Fullsizes the steering system is speed sensitive and electronically controlled, thus its gotta have a crap load of sensors, wires, and "new fangled things" that come along with it. Basicallt useless dog poop that is a pain when it breaks!

Yet another time when I'm glad I got an old truck K.I.S.S. was still in effect back then.
K.I.S.S. was still in effect back then. This is true, I wish I didn't have all that electronic crap... but my Tahoe looks just like yours (2dr, 4x4, etc). What size tires are those in your sig? Any lift or torsion cranking? I am thinking of twisting the bars an inch or so and slapping some 285's on mine.

they're 285's. little bit of cranking. I'll probably go with 265's next time, I'm not a big fan of the extra wear on my suspension and I really don't offroad much as of late, so there isn't much reason for me to have them on there.
Finally got the shaft to move after alot of Rust Eater and finished the install of the EVO Sensor... boy what a difference! Not only does the steering wheel not suddenly jerk out of my hand like it did in left turns, but the steering seems more responsive at all speeds. That thing was wore slap out! While I was working on it I twisted the torsion bars an inch and a half and put a one inch block in the back. It sits level now and looks alot better. I also took that goofy air dam off which makes it look even taller. All I need now is some 285's and she'll be set (for now). Then its a 4-6" lift and a TJM, but thats WAY in the future. Man it sucks being a poor college student!

Don't forget to get an alignment, you need it after cranking.

My Evo is bad right now, Its been bad for about 3 months, its annoying as hell when the steering jerks one way or the other, its not a real costly part to get fixed, but it it is a pain in the ass! I am just having the Chevy Dealer fix it. My truck goes in on Thursday
Well I am a poor Southern Boy so I just did it myself. Besides I am always wanting to work on/ learn about the vehicle I am driving. I got the whole front suspension out right now replacing bushings and ball joints. Talk about a bitch of a job!

You know, I hear all the time about these evo systems going out and causing control problems of the vehicle, some so bad they have to be parked till fixed. Now, this system is built by the same people that build the rear steer in the new trucks. That can't be a good thing... ow:
