Hey there,
So today I was just reminded of a problem that I have had with my pathfinder since I bought it 4 years ago. After about 30 min or more of highway driving, when I slow down to come to a light, <40kmh, I get this brutal squealing from somewhere in the front end. Sounds similar to train brakes at first then slows to almost a rubber on metal squeal stopping around 15kmh. Stops when I stop, starts when I start rolling again. Stays in sink with the speed of the drive train, ruling out the belts(which have all been replaced). Must be something heating up because its only after the highway driving and never does it just around town. Braking does not affect the sound, other than to slow it as the truck slows. 4wd changes nothing, hubs locked or unlocked changes nothing. Stops after 5 min of slower driving.
In the search to fix it I have replaced:
Front bearings and seals,
Changed hubs to Warn manual locking ones
Brakes, pads and calipers
installed grease nipples on drive shaft U joints and greased them.
Tires are new, stock and clear everything just fine.
Checked the caliper dust covers and they have clearance all around the disks
I kind of gave up looking 3 years ago(and 80 000 km) , I figured after replacing all the important parts whatever is squealing might as well just brake and save me the troubleshooting. Its hard to pinpoint due to the speed you have to be driving. Plus I hate driving for half an hour to get a few minutes of possible troubleshooting. But alas, no luck as of yet, and hopefully not in a while as I have a few road trips coming up soon. knock on wood
Does anyone have any ideas?
Cheers guys
