I know that this may be a strange question, being that I'm sure there could be 500 things causing this, but I'm curious if any of you guys have seen, or more pointedly, heard this before.

I have a 1997 Disco I, with 100k.
The brakes have been entirely replaced, rotors, calipers, and all.
On the passenger front wheel (I think, from what my spidey senses tell me) I can hear a chirping sound that increases in frequency with speed. It is constant when I am turning left, stops when I cut right, or hit the brakes with any pressure.

I haven't noticed any changes in the way the Disco drives, no steering vibration, etc.
Any ideas?
I should also point out, that when hitting the brakes hard at highway speed, it likes to pull right.....
I'm hoping this is something stupid simple....


Also, is it common for your tranny to run really, really hot? I find that my shifter is almost scalding hot to the touch after running a long time. I spoke to my local dealer, who said that the tunnel has a tendency to trap the hot air, and it's normal, but again, anyone had any other ideas?

The chirping sound could also be your front drive shaft. Check it, or have it checked before it blows-up on you. They are notorious for failing. If it fails it could take the transfer case with it. Find a shop and have them check it for play. I think rust on the caps is an indication as well.

Yeah, I figured that's what you were talking about. Last night, I went home, and slid under the 'Rover. My driveshafts both front and back are clean clean clean....not a spot of rust (or even that much dirt :) ) on them. Just for good measure, I oiled them a bit to see if lubrication would make much of a difference. It didn't. One thing I did do, though....as I stated before, it seems that the sound is coming from the right side, in front. So, I jacked her up, took the tire off, and checked it out. With it in neutral, and the PB engaged, I was able to turn the wheel, but not fast enough I'm afraid to reproduce the sound. Curiously, however, I noticed that the pad on the outside appears to be in almost constant contact with the rotor. I'm guessing this isn't normal? It seems as though the return springs on the caliper are not returning it to the proper position after braking. Could this be the brake wear tab? Does anyone know of a good source (online) of info regarding disassembling the brakes to repair them? I wasn't about to do it last night, as I never have, and had to drive it today.

TIA!!!!

AGREE! Same problem in differential. Broken teeth on the gears. Extended Warranty paid for replacement.

I think you have probably nailed your problem Penguinpowered. The symptoms you have described is the pads on you left hand side tipping the rotor as the wheel turns thereby causing the 'chirping' sound which is relative to road speed.
