i just started noticing this noise a couple weeks ago and it is coming from the back end, its a knocking noise and it only happens when i am braking from 20 mph and lower and it only makes the noise when it is wet outside and i have looked and looked for what it may be but i have no ideas at all..any information would be very helpful..

 

Sounds like you may debris inside one or both of your brake drums....or a bearing going bad.....or a worn u-joint.....or the worst case scenario, possibly a tooth missing on the rear ring and pinion.

 

sounds like you need to do a rear brake job.

 

I vote Tranny mount!

Just above your X-member

 

thanks for the help guys i will start with the brakes first and hope that fixes the problem

 

axle wrap causing noise in the ds?

 

Longhorn, inspect all rubber bushings in the rear suspension, as well. If you have a bushing worn or missing rubber you could be getting metal on metal just when under the load of braking. I had worn bushings in the sway bar cause a knocking noise under accel. and braking, once.

well guys i changed my rear brakes today and took it driving out in the snowy rain and the noise is no longer to be heard...thanks for the quick responses

 

So how would brakes have solved a knocking? just curious. What would they actually be doing to cause such a noise? I thought it would be more of a grinding as metal ate away at the drums from no padding left...what am i missing?

 

loose parts bad bearings
