Loss of Steering in turns 2002 Silverado LT 1500 Z71+
Additional Info - At 500 miles I informed dealer of thunk/thump/klunck in steering wheel in turns (with or w/o brakes didn't matter). At 6k miles she gets worse, but this time braking after the shakes starts will make for a real interesting ride (braking on straight has no symptoms). Straight aways are okay (except this morning), all the chevy trucks I've ever had weave-when-windy, but then again, all the chevy trucks up until this one could handle a simple turn (heck, a bronco II or one of those suzuki-rollover-suv's could have handled this turn better). This morning the dang thing started darting left and right on a straight away (worse then when windy). I'm driving my 1989 Silverado twinn until someone can help me find TBS info, part/assemblies to investigate, terminology, and/or other ammo to go back to dealer with. Suppose Chevy couldn't just reproduce the 5.7L 1989 1500 - best truck I've ever had in 30 years (best chevy was my 1967 ChvII Nova SS). Oh, symptoms seem to be like the 89 got at 180k miles which upper/lower ball joints/idlr arm fixed. Other facts, yes tires are GM mfgr stock (firestone AT's I think), pressure good, balanced, etc. and no I have not hit a pothole, curb, nor has it been off road yet, etc. Dealer says it is the nature of a truck - I need concrete reference numbers to go back to the dealer with (TBS, postings, something to get them to listen). And yes, after last night I'll probably spend the $120 to go to an unauthorized shop to get it checked. Could it be as simple as making the camber/castor/and toe-in closer then GM specs. Oh, as well as steering wheel clunking, you can feel the clunking under your foot when on either the gas or brake. Until resolved - I'm putting off replacing the tires with BFG AT's (Best all purpose tires and gets 60-80k+ miles if maintained, neighbors love the ride up the mountain-hill in the winter, and the tires are good for pulling the neighbors out of ditches). Oh, right turns buck/chuck/clunk more then left hand turns. Purchased Oct 2001 to help boost/support USA economy after Sept.11 (for real, no kidding): hopefully GM will help represent USA and fix the problem (lots of similiar postings on Silverado's since 97+ - so GM needs to stop sitting on it based on death/injury suits being cheaper then putting out a recall).
