I've got a rumblin' in my tumblin'
It started yesterday on the way home. I had another one of those nasty downshift clunks that occur when you decide to stomp on it to make a pass just when the car is shifting. THUNK!
I had that happen before in my previous automatic cars as well. Anyway after a short high speed run I noticed a rummbling sound coming from under my seat (slightly forward I think??). I feel it in my throttle foot as well. I don't think its a rear bearing. I thought at first it was a CV joint, but it doesn't change with steering. I drove my Forester in today because I couldn't afford to be stranded today. I need to take it out at night to see if I can figure out what happened. Drive shaft u-joint? What could this be? Ideas are welcome. Jeff

The rear wheel drive clutch may be what you hear. Under heavy acceleration it could be the pressure plate slamming when the pressure goes up.

honestly......
it sounds like your tranny mount is bad. when mine was busted i used to get the dreaded clunk. i would check that first.

Found it!
I was asking about the rummble not the clunk.
Thanks all, but it was a messed up brake caliper. I suspected as much, later, after hearing that familier grinding sound, but just didn't want to believe it. My '97 only has 66K miles and the brakes shouldn't be THAT bad. One of the front driver side pistons was stuck and was causing the brake to stick and ride the rotor. New pads, turned rotors and 'unstuck' the piston and all is better now. I see my little rubber booties (dusk covers for the pistons) have holes in them though. Should I bother to replace them? or just wait and put on new calipers when they die. All four booties up front have holes in the sample place. Is this 'normal'? I was quoted ~$85 for each caliper, with new pads included. Sounds awful cheap for an SVX part.....

It would be even cheaper to just rebuild them yourself, typically a caliper kit is around $8 each. (I'm too lazy to look it up right now ) Rebuilding them isn't rocket science, just an 'o' ring and the dust boot. Bleed the brakes when your done and voila!

Rebuilding calipers
No special tools? I don't remember how they go together, and I didn't see how the pistons are installed. I'd have to remove them?
I think I saw what looks like a steal seal ring around the piston. Is this correct? Can't I just 'push' a new rubber boot in place? If I do take them off the car I might as well paint them yellow right? Wow, you're up early.....
