My little rosy has developed a really bad rhythmic clunking sound recently, need some help identifying where the problem is. It's happening only when accelerating and gets faster and louder as I accelerate more, goes away if I push the clutch in. Had the car up on stands today to see if it were the cv's but doesn't seem likely as it still happens when the front wheels aren't being engaged. Tried turning the rear wheels manually to see if I could hear anything in the diff but no luck, maybe I couldn't turn it fast or hard enough. I had the rear diff pinion oil seal changed yesterday, could just be coincidence but either way am not terribly happy about the whole thing. Am hoping it's not the gearbox, it's about the only place I can't check at the moment.

Can definitely feel the knock if I put my hand on the rear diff when accelerating but can't tell if it's coming from there or vibrating down the drive shaft.

Have the propeller shaft checked. The universal joints could be stiff or bad.
