So, I have posted on this issue in the past, but with no luck. Redundant I know, but persistancy sometimes pays off.

2003 F-250 four door 4x4. 5.4 auto with maunaul hubs. 2009 rebuilt entire front end including: upper and lower ball joints, inner and outter axel seals, life time Waganer brake pads, Gabriel life time shocks, drag link, outter tie rod ends, needle bearings, u-joints and neoprene sway bar bushings.

My problem is two fold: The new bushings are shot, and there is an ungodly squeal coming from the left front.

Bushings are easy to replace, but I don't know what would cause them to fail so soon.

Front end squeals when stopping or reversing. I did not RTV the pads to the pistons (which explains the occassional squeal at stopping) but when I reverse the front end sounds like some one is killing a cat with a wiffle bat. The only thing that makes it quiet is by lighty touching the brake peadle. Then, today, I noticed the noise while turning a corner.

I can't think of what else to do to solve my issue. I even broke the brakes down (no uneven wear) and cleaned/lubed the slides. Noise is still there.

HELP!! I can't afford a major expensive breakdown. Anyone have any ideas?

 

My 10-year-old Contour does the same thing when going in reverse. Never figured it out other than the fact that it's coming from the brakes. Doesn't bother me.

If I had to guess I think it might be a sticking caliper of some sort. I don't care enough to replace them on my Contour, as the pads look just fine.

Hopefully someone more knowledgeable than I will chime in with the solution.

 

Do your pads have 'squealers' on them? Is one of them maybe outta whack and rubbing sooner than it should? Have you checked your calipers and the caliper bracket? Maybe something's out of alignment on those, or they are not letting the caliper release all the way. Just spitballin' here.
