November 20, 200817 yr Hey, have recently got a JDM '95 (maybe more like a '96 US model I think) legacy 250t. Got it very cheap as it needs HGs done. Anyway, I've noticed this thumping sound from what seems to be the left rear corner when driving between 20km/h and 35km/h. Thumps at the right speed to be at wheel speed. Sounds a lot like a tire with broken belts etc, but the tires are new and look in perfect condition. Also, there is no vibration at higher speeds. The noise is there whether accelerating, coasting or braking. Have also tried FWD mode and it is still present. Any ideas on what it might be, other than a bad tire??
November 20, 200817 yr Rotate the tires to the front. If the sound moves with it, you know it's a defective tire. If it doesn't, then one possibility is a rear wheel bearing.
November 21, 200817 yr My only idea would be an out of balance tire. But maybe some kind of differential problem or wheel bearing...have you checked the tires?
November 21, 200817 yr look at the rear axle shafts: make sure CV boots are intact. Although less common than front axle CV joint failure, rear axle joints can go bad. If it's "one clunk with every revolution" of a wheel, I'd look carefully at those axle joints.
November 21, 200817 yr i have the same thing in my 96 Legacy. I converted it to FWD, removed the axles, and replaced the wheel bearing and the same exact sound still persists at the rear drivers side wheel area like you said. must be the tire on mine, not sure yet though.
November 21, 200817 yr Author It is a wagon, so there is definitely no one locked in the boot.... Will certianly do a tire rotation when I get it back from having it's head gaskets done... But in my experience, for a tire to make that much noise it has to be pretty bad, and the damage is quite visible. But maybe something strange has happened to it.... It does still seem the most likely culprit.
November 22, 200817 yr Hey Ross, what kind of rims are you running? The stock JDM 5 spoke rims are prone to warping very easily. My only other idea is a broken lug nut? Or something inside the park brake hub. I cant remember how much clearance is between the rear caliper and rotor - but having a stone glued to the inside of the rotor makes a similar noise as it hits the caliper on each rotation. If you raise the wheel off the ground and spin it by hand do ya have any resistance? Edited November 22, 200817 yr by keltik
