2000 chevy tahoe: you adjust the steering box..tight..tie rod..tires

Customer Question

can you adjust the steering box on a 2000 chevy tahoe. Truck wonders in the road and everything seems to be good and tight on the tie rod end. have also tried rotating the tires. I think it may be in the box. I know back in the 70s you could adjust the worm gear and tighten up the stering.

HelloCustomer and welcome to JustAnswer.com!

YES! This gearbox can be adjusted, and its design isn't much different than what they used back in the 70's. The procedure for adjusting this requires removal of the gearbox from the truck, centering the stub shaft, and making the adjustment until it takes about 10-12 inch pounds of torque (using a torque wrench) to rotate the stub shaft.

Realistically, if you can get to the adjuster bolt (refer to the following illustration), you can try tightening it 1/4 of a turn at a time and driving it. If you get to the point to where the steering wheel doesn't want to center, or the steering gets too touchy, then you've gone a little bit too far and you'll need to back it off a little. If you leave it over adjusted, you'll experience premature failure of the gearbox.

Before messing with the gearbox adjustment though, you need to make sure you also check your ball joints and control arm bushings. Jack each wheel (one at a time) from under the lower control arm, as close to the wheel as possible. Push in and out at the top of the wheel, while observing for horizontal movement in the upper ball joint and control arm bushings.

Then use a prybar to pry upwards from underneath the tire, while observing the lower ball joint for any vertical movement. Any play at all in these components can cause wandering, noise, pulling, and irregular tire wear. You don't want to risk damaging your gear box until you're sure that is the problem!

Good luck!
