Suburban Alignment

[wlhump]

I can't seem to keep my 2001 'burb in alignment. It constantly pulls to the right. I have had it aligned twice and that helped for a short period of time but each time it eventually turned into pulling to the right. I have the worn inner edges on the tires like almost every 'burb I see down here. (I live in Lardeo TX which must be the Suburban capital of the US. It seems that 2 out of 10 cars on the road are 'burbs!)

Has anyone else had a similar issue? I would hate to think it's my wife driving into parking blocks.

Almost forgot: when turning slow speed to the right, at full lock, sometimes it feels like the tires will "flop" to a tighter turning radius. I have only noticed it on right turns.

Thanks for any help.

Initially thought tread seperation, but since alignment shop visit "fixed" it for a while...

 

How many miles and greased all 11 or 12 zerks on regular basis, like at each oil change?

 

Inner tread rib wear on both indicates too much negative camber. By chance after market wheels with lots of offset?

 

Could also be stuck caliper piston or collapsed caliper hose holding pressure on right side.
