14BFF with a Detroit Locker. 2" spacers. Caddy Calipers. Sounded great last time I drove it. Sat up for 3 months.

Today it is making a loud "ratcheting" noise as I drive forward. It gets faster as the truck goes faster. Click, Click,Click....

It does not make the noise much when coasting, but makes it loudly when accelerating.

Seems to be coming from the rear axle. U-joint is tight. No vibration that I noticed.

Someone stick a socket wrench in your rear diff?

Locker enguaged half way?

 

[Flatline's Up!]

rock in your tire? :flipoff2:

I can't attach the .mp3's here, so they are here so you can hear it in action.

 

[Flatline's Up!]

got any "friends" that would have hidden some rocks/nuts/tools inside one of your wheels?


*not that I condone that mind you nor have I ever done so :shaking:

did you check the diff fluid? sounds like the locker.

I know its far fetched but check for zipties on your drive shaft somewhere. This asshole that hangs around my one buddies house did something with zipties on my friends truck and when you drove down the street it sounded like something was really fucked up.

No pranks, no rocks in the wheels, not even one of my kids "helping" by putting a screwdriver through the u-joint and leaving it.

I'm thinking that it is the locker. I filled the diff whe I installed the axle a few months ago and have very few miles on it, so the fluid should be fine.

check the u-joint and the u bolts if it is not greased it could be starting to come apart

 

[fatboyf150]

are you driving straight or in a circle when it makes the noise. jack it up, put it in drive and go listen to see if you can find it

 

[GMCTruxrule]

Sounds like u joints to me. Double check. Jack up the rear tires and rock the driveshaft back and forth.

are you driving straight or in a circle when it makes the noise.

Driving straight.

I am not saying anybody is wrong, I am throwing this way out in left field, Do you have an auto trans? Are your converter bolts tight? I have had that noise before, and it was the fins on the tc rubbing the bell housing.

my .02
good luck

those get WAY loud when the get loose. and it would be coming from the front/middle of the car.

 

[Chevyman70]

My blazer had the same problem, its probably u-joints.
