Noise... I'm clueless

[4.0B2]

On the b2 I have a weird noise when I am on the brakes hard. It's in the front front left. Sounds like a budging compressing or a pop or something. Idk how to describe it really. But it's only when I'm hard on the brakes or taking off heavy...

Checked your bearings lately?

 

[4.0B2]

I have the right side! Lol..... Not the left would it make that sound tho? Like something being smushed together, compressed... Almost like the radius arm is lose? But it's not

Radius arm bushing?

 

[4.0B2]

Those are fine.. I almost think it's the body mount. Like it's lose or something. Gonna look more tomorrow and recheck the radius arm bushings, might just change them anyways

Does it make a noise if you go over a bump? Like pulling into the driveway or speed bump? My RAB's made a clunk when I hit a bump.

Are they fine because they look OK or because you have changed them recently? They won't move around with the vehicle just sitting still because they have a lot of weight and tension on them. Usually the hole in the middle where the arm goes through wears and you can't see it. One of the primary reasons to have radius arms is to absorb movement when braking so that would be the most likely thing to look at.

They were changed about 8 months ago. I'm gonna change them again bc the there is nothing else loose. Nothing else makes sense to sound like that. I've been out there since 7 doing random things, looking for this noise. The only thing I found out was it also does it when I'm on the throttle heavy and it shifts hard

stock dana 28? did you check the pins that hold the caliper on? and the caliper bracket for wear where the pins go into?

 

[Shran]

Motor and/or transmission mounts? Would make sense if it happens when it shifts.

Ball joints?? A loose joint will allow the knuckle to move when braking.

Idk I'm gonna tear it down this weekend this Saturday and see what I can find. Thanks for the input guys. I just thought someone has encounter this before and could say it's this.

you might check the keeper pins on the front brakes.

Hm. I actually had a similar thing happen with me, and I never pinpointed it exactly. I redid my brakes and suspension one day, and it went away. *shrugs* I redid everything, from caliper removal to upper spring seat.

I COULD be a balljoint.

hmm... i need the coil spring rubber isolater thingy... just saw this.. i hvae no rubber isolater?
