Ian, Doc, or anyone;
My wife's 97 Yukon has a steering problem in that sometimes during a right
hand curve at about 35 mph
the steering effort increases slightly then decreases enough to make her a
little uncomfortable driving
the truck. I can feel it sometimes and at first thought it was something
similar to when one of the axle
U-joints on my 87 K5 got stiff, although it doesn't dive to the side like
the K5 did.
The local shop had it on a lift and checked the front end, but found
wrong. I read the thread about a bad EVO sensor and am wondering about a
simple test I could do.
If there is such a test, where do I find the sensor and aprox how much would
a new one be in US
Basically, you've done the simple test. If it feels like
the steering overassists in the corners intermittantly, I
would say that it's very likely that you need the EVO
sensor. It is located at the base of the steering
column, you need to disconnect the intermediate
shaft (still inside the vehicle) and move it down just
enough to be able to take the sensor off the column
I'm not sure of the price, best bet is to phone a
It's a simple job, I just did my '97K2500 over the Christmas break, took
about 1/2hr from start to finish.
You need to remove the pinch bolt at the base of the column in the
truck, then push down the shaft, then locate the three plastic fingers
that hold the sensor in place and while gently prying them open, pull
the sensor out..oh yeah..make sure to disconnect the little quickie
elec. connector, mine was under some padded sticky stuff stuck to the
side of the column right next to the sensor..
Pretty easy once you stick your head under there with a mirror and see
whats going on...
