    i have been having steering issues but i think that frame could be cracked. its a 1990 3/4 suburban, 4" lift with 35s. what happens is the truck will pull hard to one side, if i jerk the steering wheel to the opposite way, it will begin to pull to that side. but inbetween all this, sometimes it will drive in a straight line.

    I looked around the steering box but couldnt see anything, but i really should take the steering box off and inspect whats under it right? From searching i have found the ORD steering brace and repair kit which i am going to buy. Just wondering if this sounds like it will fix my problems for if its something else. thanks!

    i would have someone turn the wheel while you inspect the steering box, watch it closely, and see if its walking off the frame, thats what i learned in my research a while back

    Symptoms of frame cracking? Cracks... Just look at the box mounting from under the vehicle.

    check the balljoints too. have someone sit in the truck and see saw the steering wheel and see if there is ecessive wear in the balljoints. Also, grab the tie rod and see if you can move it (rotationally) by hand easily. These could cause you steering greif as well. Check your fluid level. If you don't see a crack on the backside fo the frame then it's not goign to be cracked on the other side behind the box either. Make sure the bolts are tight and check your steering column. The joint that meets the box could be toast too.

    I agree with the ball joints, a little play is all it takes. Had it happened to 2 trucks.

    3/4 ton 1 ton 50,000 ton, they can all break. Did you find anything out yet? Don't ya hate it when there is a ghost problem!

    RIght now i'm dealing with what i thought was the transfer case losing a bearing. We took the case apart, rebuilt it, noise was unafected! Ugh. Clattering so loud you can't think.
