Truck Hard To Turn Left...

[sciggs]

For about the last month, my truck has been extremely hard to turn left at slow speeds. When I'm not moving or barely rolling, I can barely get the wheel to turn left. It turns right fine. I checked my power steering fluid and everything seems to be fine with it. Someone mentioned that it could be the tie rod. Is this a possibility? Does anybody have any other ideas of what this problem could be?

Get it on jackstands (preferably under the control arms so the steering geometry is about right) and see how things move without power assist. That'll tell you if anything is binding up. If all feels good, then it is probably an issue internal to your gear box.

I will have to try that and see if I notice anything. Thanks. It makes a strange noise too when turning left.

Another old thread I am resuscitating...

 

How can I determine if the issue (I am experiencing the same thing with my '01 Suburban) is with the tie rods vs. an internal gear box issue?

 

OP's symptoms sound just like mine...

It could be a bad EVO sensor also.

I had a bad one on my gmt-800 replaced under warranty.

The dude hasn't been around in almost 2 years so hopefully has found a fix or given up trying to find the problem. My truck it was opposite, it wouldn't turn right sometimes. I knew I had some worn parts in my steering so after replacing them my problem has seemingly gone away. Tie rods were fine, my pitman and idler arms however were a mini "swing set" under truck so I figure they were probably toast. Plus my tires are not wearing funny anymore either, smoothing right out.

Do you have a part number for the evo sensor? I can't find any additional tech info on it...I am able to find, on some other forums, some discussions about it but nothing technical.?.

 

I found that you can use a multimeter to measure the signal when the steering wheel is used. The theory being that the multimeter will show steady readings for a healthy sensor and will show erradic readings for one that is bad. Do you know if this is the case?

I personally have no idea. Maybe Rob will come back & tell you for sure.

i remember something about the EVO sensor being the problem for something ,ive never heard of hard steering one way being the EVOs fault

 

if only chevy tech would chime in .....

 

it may be the steering gear ,IDK

 

dont throw parts at it..

 

this is an interesting problem,.....dealer has evo p/n,,they sell them you know lol

Again..........READ the link I posted and my "high steering effort" at idle issue.

MANY of the same issues posted here with the EVO sensor problem and related TSB.

 

Again with several possible causes a dealer visit and proper diagnosis is

your best bet.
