Front end noise?

[Sport 4x4]

My 92 Sport 4x4 is making a weird noise in the front end. It's like a combination squeak/scrape. It doesn't do it all the time and the more I drive it goes away. It sounds like a bad bushing somewhere but I'm not sure. The truck seems to drive fine other than that. Next month I'm getting new wheel bearings and brakes put on it but this noise has me puzzled. Any ideas? Oh, and it does it mainly as I hit the brakes but not always...

Could be radius arm bushings. Mine squeeled a lot. Thought it was the rubber ball joints(also posted here). I first injected some oil into the ball joint cups. That did nothing.

Spary some WD40 on the RA bushing to see if it goes away. My noise came from the arm scraping againsed the frame mount. This is not a fix. It will come back.

If you decide to replace the RA bushings yourself, There is loads of info on how to do it. I did mine. The first method didn't work dropping the front end. Next I did the grinding thing and ran into trouble banging out the rivets. I ended up drilling out the last two using a small drill first all the way through the rivet creating a guide hole. I then used a larger drill to cut out most of the rivet. At that point you can use a chistle to colapse the rivit and knock it out. This is definately the easiest way to do it and you don't need to buy a grinder. The rivet metal is too tuff to chistle off the head. But it is soft enough to use sharp cheap drills. Just don't put much pressure on it when drilling, and just give them time to cut through.

I've had bad brake pads make a similar squeek/scraping noise. You might want to accelerate that brake job, and see if it's just the rotor rivets dragging on the rotor.

I'd be more accepting the fact the pads might be shot if it did it all the time, it seems to do it more when it's warm I dunno...
