I read a post earlier about wandering steering, and my problem is similar sometimes (Like tonight) i start to drive and suddenly the front wheels jerk to the left then to the right over and over .It almost feels like i'm driving on very slippery ice, and needless to say the drive home is very nerve wracking. A couple of months ago i had the pitman arm, and the tie rod ends replaced , and the problem seemed to lessen however now its back. My truck is a 1979 surburban
1500 with 4 wheel drive, and a 350in engine. A local midas mechanic who replaced the front end parts stated (After i told him the sterring still wandered) that he had an older chevy 4 by 4 similar to mine , and the locking hubs would "Back out" putting the truck unintentionaly into 4 wheel drive and the truck would swerve suddenly like mine. I'm stumpted (And afraid to drive my truck in traffic) any thoughts???... snipped-for-privacy@mindspring.com
