Just picked up a '94 Sidekick JX from a relative.  He gave it to me for nothing because he was too lazy to fix it or sell it.  He told me all it needed was a clutch job.  It has 145k miles on the origional clutch.  The symptom is that it whines like hell when the clutch is out, but is quiet when you push the clutch in.  Everything's origional on this car; engine, trans, t-case, clutch.  I haven't driven it around yet so I don't know if it makes any noise in any particular gear, but he says that the whining goes away once the 'kick warms up.  Sound like a bearing in the trans or a throw-out bearing?  I've searched this and a few other suzuki forums and found both explains the sound.  Any ideas?
Thanks,
WES

if you push the pedal to the floor and it stops whining its the trans bearing

That's what I thought, too.  Is it time for a rebuild/replacement?  What about draining it and adding fresh fluid (it's probably never been changed!)?  Maybe adding some Lucas Oil to the new fluid?  Any other ideas? 

Thanks again,

oils cheap . i'd try it. when i got mine i drained the oil. it had alot of water in it. 
it almost looked like mud.  flushed it out good and now its fine

Mine does the same thing and it whines when driving in 5th gear.  Neither are too bad yet and I don't get many miles on it so it'll wait till I go through the engine.

Mine does this when cold. I warm it up with the clutch pedal to the floor and it makes no noise and after warm it's fine. Hoping it will not be a problem for a while

Same thing here....why does it stop when it warms up??  Wouldn't a bad bearing still be bad regardless of temp?

My guess is when what little lube there is left gets warm, it lubricates better and the noise goes away.
