Hello,
Both front tires on my 04 Ram has excessive wear on the outside edge. I got a set of good used tires and went to get an alignment. The shop said that it was due to camber, toe-in. They said they cannot align it because they need a kit that contains a concentric to get everything set to spec. They said that the factory doesn't come with this and that I need it. They also said that Ford's are the same deal on this. I wouldn't think that the factory would do this, but then again...strange things happen. I will also mention that I bought the truck used and that the dealer did say that it had a front end accident and that they needed to replace some suspension parts on it. I cannot remember exactly what parts. The thing has no wobble or pull or anything that feels hinky. Just wears the tires like I mentioned. Does the shop's solution sound plausable? They have always seemed honest to me and they have a good reputation around here.
Thanks.

 

Go to another shop. Its not needed and they are just trying to sell you parts.

 

I've had mine aligned twice and neither shop has mentioned this.

 

Feeling a bit dumber than usual...I guess I meant eccentric, not concentric. Found an older thread about camber adjustment and ball joints. The shop said it would be $50 per side to install these so they can get everything adjusted properly. Sometimes the old noodle just don't think so good. HA! Anyway, hoping to get alignment squared away tomorrow.

 

Its not needed, dont wast the money. They do not add and more adjustment. They just make it easy (actualy faster) for the tech to do the aligment and thats it.
