Thread: Mysterious noise driving me crazy!

If the pads don't solve your problem I'd look at the u- joints even though you say they are brand new. One bad needle bearing could be the culprit.

Good point, that could definitely be another source of this weird sound. It has crossed my mind that could be the source. I greased the u joints after the sound first appeared, but it didn't seem to make any difference.

Not sure if grease would temporarily prevent the noise or not, if in fact it was a bad needle bearing? Any idea if that would make a difference?

I don't think grease would make a difference. I had one on a 91 Dakota that would howl mostly over 45 mph, but hardly made a squeak under 45

Just a thought, try the zinc grease and put a slight chamfer on the leading and trailing edge of the pads. If you have access to a hoist you could run it up With the wheels of the ground and see if the noise is in the drive train or not.

Has anyone metioned axel bearing, new bearings in the rear were more then likely the carrier bearings.

When i fitted the rear discs to my 67 i noticed the length of the bolts that hold the axle flange in place was an issue. If the tail of the bolts faced towards the inside of the disc they would just touch the inside of the disc when rotating. I turned the four axle flange bolts around and the clearance issue resolved itself. Just something to check. This may be only a problem with the kit i have.

That's a good one something rubbing back there, it does not sound like a brake problem the sound is not changing when they are applied.. If brakes are dragging you will smell them cooking and feel the heat when you walk up on the wheel. Sound goes away at very low speed, low speed low load, sound from the rear. An axel bearing will do exactly that, I do like the long bolt possibility suggested above it would be worth checking out.

UPDATE
After several inspections to locate this mysterious noise, all of which failed to detect exactly what was causing it..it just suddenly stopped one day.. Ghost in the Machine I guess?

I've now driven a couple hundred miles, still quiet.. thankfully.


Appreciate all the help and suggestions.

Sometimes the best solution for a low, unexplained noise is to turn up the radio. If it gets worse, it'll get louder...
