1973 pinto wagon... 205 70 14 tires 82000 miles on factory suspension, new tie rod ends 7000 miles ago
I hear a popping noise and a small jolt when backing up with the wheels turned fully to the lock.
No steering problems otherwise, no while shimmy at speed
Alignment good tracks straight on the road, I can take hands off steering wheel at 70 mph qnd car tracks straight
I have inspected the front suspension and have had it inspected by an alignment and suspension shop and nothing seems loose, bent or broken.. some play in the lower ball joints..wheel bearings tight, new sway bar bushings, no play in steering rack.
Only happens when reversing with wheels turned to the lock.
Could problem be that the steering geometry causes the wheels to set to a non parallel track and the oversize tires then deform rather than slide and then "pop" back into place.
This has occurred since i bought the car in 2016 7 years with 62k miles and hasnt gotten and nothing has broken
Any ideas?
