Hey all. I'm rather new to the e30 world. I've got an 86 325es with a manual tranny. For the last couple weeks I have noticed while I am leaving a stop sign or traffic signal...if I press the go pedal any harder than granny speed I get this thump thump thump comming from the floor. So long as I baby the go pedal to get up to speed it doesn't do it....its only when taking off from a stop or I suppose when I put alot of strain on the driveline like going up a steep incline in any gear with low rpms...... I recently had tires replaced and happened to peek under the car while it was in the air on a lift. The guibo appears to be fine, no tears or cracks or loose bolts etc...turned the driveshaft by hand to check for play in the u-joints and they seem ok....didn't think to wiggle it at all but I'm thinking its possibly the center support bearing. Was just wondering if there is anything else I should check whislt I am under there this weekend poking around should the center bearing happen to check out fine....
Thanks in advance, Eric
