after taking my car to track on slicks 5 passes in the car started jerking and popping when turning , i thought it was the axel so i replaced it and it still does it ! what could it be ? im lost it also does it when im going around 45 miles a hour it willl jerk randomly from the passenger side but it does it worse when turning

 

Hmm my first guess would have been the front right axle also because I've experienced the same thing recently on my driver side one. Did you replace it with a brand new axle or a spare one sitting around? Chances of two bad axles are slim tho. Maybe jack up the front and do some pulls with it up and have someone look around the wheel well to see if someone thing seems wrong?

 

im guessing its the mid shaft or differential
what do you guys think ?

 

u can check for play jack the car up and wiggle the axle going into the tranny to see how much play u have up down side to side.

 

i checked the other day and their wasnt much play at all .

 

how r ur bushings? check ur wheel bearings?

 

sounds like the diff. check the tranny oil if it's dark and has metal bits in it you need a newone
