I've had the Runner for a while now. There's a little problem that's starting to bug me. I've noticed that under hard braking it feels like the wheel is shaking. Also i would have to hold the wheel to make it brake in a straight line. Could this be the wheel bearing? or another problem? how would i know if it's the wheel bearing? i know replacing that could be a PITA. i took the t4r for a wheel alignment to see if it would change anything but problem stayed the same.i don't really know what's up with my t4r.

 

If you notice it shaking only while you are braking then you should check to see if the front brake rotors are warped.

 

i would check/change the rotors and pads. maybe your calipers are going bad? i wouldnt think it would be a wheel bearing

 

Steering wheel shaking under hard braking is usually a sign of warped rotors. The 4Runner OEM rotors are prone to warping. If you do a search, you'll find a lot of info on this.

Many forum members have replaced their OEM rotors with Brembo standard rotors and various brands of brake pads, although I consider the OEM pads to be decent. I currently am using the Performance Friction pads and find them to be a mild improvement over the OEM. Research this and I think that, once you know what you're looking to upgrade to, you can call around to various shops and get a good price (assuming you don't intend on doing the work yourself).

I paid about $100 for the 2 rotors (incl shipping) and $29 for the pads at Autozone.

 

i hope it's not the wheel bearing. thanks for the help guys. i'll make sure i check the pads and rotors.
