i have a 91 awd safari when i back out of my driveway hit the brake then turn right while not moving i get this real bad grinding noise sounds just like brakes but the van is not moving the noise goes away after i start driving even just a little movment stops the noise ive been a mechanic for about 9 years this has me just stumped

grinding huh? well i would check 2 things:

1. I would make sure that my front tires weren't rubbing anything while turning.

2. maybe the noise you hear is your brakes letting go as you just start to move. i know if i take slight pressure off my brakes when applied, it can make an awful noise.

Good luck

Hi allwhite1100
Hmmm, If the above mentioned doesn't shed any light then the next 2 things that come to mind are 1- your sliders on the calipers maybe seized or stiff or 2- your ball joints are worn. You should have them both checked by yourself or someone knowable in that area (Front Ends). Just a thought.

any luck?????????

no luck with the brakes replaced callipers and rotors same noise next im checking steering gear box its the last thing it could be

 

[coolen]

did you have the ball joints checked?

That's really odd. My '89 started doing the same thing yesterday. My driveway slopes pretty good and the grinding noise only happens when applying the brakes in reverse on the left front wheel. No noise going forward. This weekend I'll pull a wheel off and have a look. Be interested what you might find.

I FOUND THE PROBLEM but have no clue on how to fix it my ball joints are grinding aginst the rotors but both are tight yesterday my wife was driving and got pulled over the cop said she was shooting sparks when she turned. anyone know why they could be touching

:shock: WHOA!!!! :shock:
The only thing I can think of is wrong parts maybe? Wow....

Pull that van off the road now! Is it the upper or lower ball joints? May also want to check your wheel bearings.

Pull that van off the road now!....

I have a feeling that's what the officer said!

Any news?

 

[allwhite1100]

yeah thats what the cop said i raised the van back up and cant duplicate the sparks but the grinding still exsist the lower ball joint is actually pushing the backing plate against the rotor so not ball to rotor contact but thats no better this weekend i will replace bearings hopefully that will fix the problem I NEED MY VAN

can you take a picture of the whole assembly? I can't believe the ball joint is that close to do that.
