hes got me too

 

I'd say if he knows someone that has a true flat block (I can't remember what exactly they're called but they're used for determining warpage and whatnot in low tolerance applications) I'd say take the rotors off and check all 4 of them. Also check the brake calipers maybe one of them isn't working right? Check the pistons on the calipers see if they're cocking when coming out. Possibly check the bolts that hold the caliper in place? Those are the last things I can guess...

 

so why dont you spend 20-30 and get the front rototrs turned?

 

Most places now a days won't turn rotors. At least not new rotors because the new rotors are made witha softer metal. I read an article in a magazine once about this. When they stopped using asbestos in brake pads they had to use a softer metal for the rotors to stop the squealing when you hit the brakes. So instead of turning rotors they just recommend replacing them.

 

any macine shop will do it i just had mine done on a 4 runner they said as long as the roters are thick enogh they will do it. 15 a roter.

 

We never turned rotors but then again with the safety inspections here they're pretty strict on rotor thickness and most people don't bother thinking about rotors until it's too late.

 

dont get me wrong i suggest he gets new ones but just to see if they are the problem here do this go to a junk yard and get a pair that look stright see if they work if the shake stops or just turn those ones.

 

Now that's a good idea. I hadn't thought about snagging a pair from a junkyard and trying them.

 

The rotor were ground here at work. Big machine shop and it helps to be tight with the machinists, and be a former turned design engineer. So every body is focused on the rotors. Why that They are ground and run true by the indicator.
Is that they only componant on the front end? does anyone know about the bushing situation on the front or has no one ever had any problems with that in the past?
Any steering lash adjust or other variables that would cause a similar condition?

 

have you checked the half shafts? it maybe that one of the joints that is under the rubber boots is or has gon out so bad it is causing a lot of front end shake.
