I have a 1992 Ford F350.Just replaced the rear end. It still makes a clunking noise when I put it in reverse. What could it be


the "backlash" felt by reversing the drive shaft direction is normally the clearance in the spider gears in the diff so to get rid off that ( not necessary unless it is excessive) is to pull the diff center out and fit new thrust washers behind the spider gears
next check the diff mount bushes as the diff reaction will move the bolts in the mounts and make the noise

Heard a clunk while driving diesel ford excursion now when drive and reverse don't work....any ideas what problem is?


If it is a four wheel drive check your tail shaft or drive line by securing the vehicles front wheels jack up the rear tires and in park try to rotate the drive line if you can hear the transmission sound like it is going into gear the transfer case could be damaged! If not a four wheel drive pull the transmission dipstick and look to see if the fluid is dark red or metallic grayish color if so then you're clutch disks inside the tyranny have been worn out and it needs to be rebuilt!

Jack the vehicle up by the pumpkin and use kickstand to support. Turn the wheel back and forth and you d should be able to isolate. It sounds like a gear in reared or wheel bearing

My 2000 model mazda protege makes a clunk when making sharp turns, accelerating or shifting from 1st to 2nd gear?


Sounds like a bad cv joint. Easy way to check is to raise the front of the vehicle so both front tires are off the ground. Use jack stands under the vehicle and block the rear tires. Start the engine and put the tranny in drive. Let the front wheels rotate while the engine is idling and turn the steering wheel slowly in both directions. Listen for the clunking noise. You may have to speed the engine up a little to make it work.

Sounds like a clunking noise, like the sound you hear when you have a flat tire, Tire isnt flat. turning right on the wheel lessons the sound but stays the same turning left. noise seems to be getting...


its a wheel bearing. .will need to be inspected to determine the correct one. Also tires could also do this if the steel seperated internally. Rotate the suspected tire to see if it follows the tire.
