My V8V with 90k miles is becoming a little squirrelly under hard acceleration. It always was a bit, but now is becoming more pronounced. I am on my 3rd set of PSS since switching from Bridgestones and i do not believe it to be the tires. Everything seems solid when on lift. Anyone else experiencing this issue ? My car is 07 before suspension ***'y changes.

 

Check suspension bushings and shocks, shocks can really mess up traction when they go south.

also, why so many sets of tires, do you have a lot miles on the car?
If you are eating tires, sounds like you have suspension issues.

 

90k miles and did loose some life on the fronts due to warn tie rod inside ball joint. Around 20k per set is what I average.

 

If the the happy tail feels like a hop, I would say shocks, else my bet is bushings, either in the sway bar or control arms.
Also, check the alignment and air pressure in both rear tires and the rear hubs for excess play.
