I have a 99 jet viper on an impala stub I am having a problem on the right front. The tierod is rubbing on the center link right behind the idler arm when the wheels are straight. Car was on the frame machine and everything was ok there. I replaced both upper and lower a frames on the right also changed the spindle,inner and outer tierod ends and adjusting sleve and a new center link and idler arm. With all that it still rubs. I go get it from the frame man tomorrow and the only thing left I can think of is maybe the caster is way off. Any help would be very much appreciated

Maybe your parts man has given you the wrong idler arm.There are a few idler arms that will fit that are within a 1/2 in. of each other in length.Double check with another brand to see if there is a difference in length. It is also possible that the idler arm mount area is bent.If all else fails give Jetmod a call.Has the car been in a crash where the lower a-frame has taken a hard hit? Maybe the rear a-frame mount is bent or even the a-frame.Check it out. Dman

I called jet and every bolt on part is correct it was on the frame machine yesterday and everything there is straight. I have replaced everything that bolts on the front end and still have the same problem.

Have you verified that the replacement parts that you put on the car were actually the correct parts and not mis-packaged? I've had this happen before with seals and tierods.

Is it possible to check and make sure the idler arm and pitman arm are the same lenght? It might be a way to double check since something is not right even if the parts number check out ect.....having different lengths would also screw with Akerman. Can't imagine that camber could cause it to rub since the lower ball joint is fairly close to the tie rod/spindle.

Did the frame shop check the lower a-frame location? Usually they just use reference marks on the frame when they straighten it. Dman

The pitman arm is about 5/8" shorter than the idler arm. I called jet and he measured two of theres and said that is the way his are also.

My frame man hung the guages on it and everything is ok. He measured the upper and lower a's on both sides and the right upper and lower are actualy 3/16ths farther back than the left side is. But that would give me more room.

Assemble the front end and start measuring things till you find it. Any idea if the Gear box has been relocated fwd or anything of the like?

Just thinking out loud to try and help. I had a similar problem but found a swedget tube bent up, so that was it. Although its still not perfect, and continuing to try and locate the troubled area.
