drift under acceleration

[Canyon Man]

Hello,
i just finished replacing upper a arms , upper and lower ball joints, inner and outer tie rod ends, and new wheel bearing hub assemblies. When I am driving and acceleration the vehicle will drift to the left and when I ease up on the pedal it goes back and everything is fine.

Did you get wheel alignment after changing parts?

 

[Canyon Man]

yep, wheel alignment was done right after the parts where installed

double check everything is tight. and i think the front wheels are digging and pulling you over.

sounds like the caster is not set properly
