I took my 2004 TSX in today to have the Camber TSB performed. The TSB states to replace upper arm if the right rear camber is greater than -1.0. Right rear camber was -1.1 before and -1.3 after the arm was replaced. I don't understand what the new arm accomplished. Any experts out there???

 

What is the complete before and after alignment spec?

 

Here is the printout they gave me.

 

Your right rear toe was out of spec., but not your camber. Anything between -1.0 and -1.5 degrees camber in the rear is within spec. The toe was the issue, so you really had no need to have the TSB performed, on an alignment.

 

That's what I was thinking. Acording to the TSB numbers I was a candidate for the new arm because my rr camber was greater than -1.0. Now with the new arm it is even further away from nominal specs. What a waste of time.

 

Notice how the rear left camber changed from -1.3 to -1.2 without any work done to the left upper control arm? Your original rear right camber was actually fine at -1.1 even without the control arm replacement. The camber setting will change slightly from a full tank of gas or a trunk full of stuffs. That's why there is an acceptable range which considers to be within spec. The front and rear toes were the problem areas.

 

Atleast I got a free alignment out of the deal.

 

-1.1 and -1.3 are not greater than -1.0. Sounds like the spec is -1.0 to -1.5. -0.9, for instance, is greater than -1.0. Do they really mean "greater than"?

 

I think they mean further from 0.

 

That's initially what I thought. You're probably right, just an observation.
