Gentlemen, please help ...
I have an ExI from 1994. I have restored it to the factory condition, but I can not get rid of one problem. When adding and subtracting gas, you can hear a rhythmic knock at the front of the car. (identical when dealing with broken wheel bearings. You have ideas what it can be?
I replaced everything in the suspension: left and right wheel bearings, suspension bolts, crosses, undressed rear axle.
Surely there will be someone with more experience and tell me what else to check.
