Hey guys, my 83 GSL has developed a vibration/sound during low-mid speed right turns. Seems more prominent under braking. Any thoughts/ help appreciated.

 

possibly rotten bushings causing metal on metal contact.

also..vibration under braking can be caused by warped rotors(have them turned if still within spec)

or it could be bearings...


start off with a good visual inspection of the front undercarriage.

 

Sounds like front wheel bearings to me. Have a friend on that side confirm that it's coming from the wheel and you're probably well served to change front wheel bearings on BOTH sides - if one side is bad the other is sure to follow.

Wheel bearing change is straightforward work, and the parts can be found through VB or Mazdatrix at good prices - about $50 per wheel for both bearings, inner and outter, and the oil seal. Get new parts all around to be sure that it works correctly. Another $3 for cotter pins of the correct size, and you have all that you need, short of a bearing greaser and a grease gun. Do not reuse the cotter pins to avoid any potential problems with the metal fatiguing and breaking off the cotter pin - which could allow the stop nut to turn loose - oops, there goes a wheel/tire...

Removal of the hub is easy enough - check on search to find the torque specs for setting the new bearing pre-load and getting them done right the first time. We had a thread open on this about a month ago when I did my front wheel bearings and learned a few things. HTH,

 

Thanks guys. I had suspected it was the brake rotors, but when it started occuring without me applying the brakes I got a bit worried. When the snow melt here I'll take a good look at everything, thanks again!
