I almost put the wife's car in the ditch taking down a Audi one afternoon, I've never had a vehicle come out of control like that. I had one front tire slightly lower on air than the other and chalked it up to that. Wife kept saying it drove scary sometimes. Drove it again one day and it would give a little yank to the right EVERY time it shifted to third driving normal, couldn't hardly punch it anymore without one hell of a firm grip. Heard a slight rattle on bumps from the front right so started investigating. Inner tie rod had ever the slightest amount of play was all I could find, to the stealer she went. After ALL day and half a tank of tire burning fun, they figured it out. Found a bolt on the front end that had slightly backed out, a little Loctite and ran it back home. Drives like new again. I asked what bolt but the guys were packing up for the day and I was tired and hungry, he told me they said you couldn't even see the bolt had backed off some and they'd found it by just going around and tightening on everything. I bought the two mechanics and the service writer lunch the next day, most dealerships would have never found something like that...if the even tried at all.
