I have a 89 4wd pickup 22re past few weeks ive had a chatter noise coming from the front only while driving. So far Ive checked the pulleys,wheel bearings,greased ujoints,checked brakes for debris but still cant find the cause. Any input would be much appreciated

 

I should add within the last year i have replaced the timing chain and cover,clutch,throwout bearing. The chatter first started while downshifting now its consistent

 

Check the bolts holding the rotor to the hub. Mine backed out and caused a chatter then a rattle.

 

Do you have auto hubs? Those can make a chatter sound. Maybe check the your fan shroud.

 

Checked the rotors when I inspected the brakes, I actually recently put the fan shroud back in after swapping out radiators so that is a possibilty have to check it out tomorrow can't believe I overlooked that one thanks

 

A loose skid plate, splash shield, etc?

 

Wheel well liners? I have had that one way to many times!

 

Checked the fan shroud,skid plate,shield,liners are all good. Took it for a ride today and the chatter acts up the most when I let off the gas and goes away when I engage the clutch so I'm thinking maybe I got a faulty throwout bearing
