Rear axle knocking sound

[Mux213]

Hey Guys,

Okay I got another weird one on the rear axle, since last few days on decelleration I sometimes hear a rear knocking sound coming from the rear axle. Sounds like somethings loose.

I drove past the Toyota dealer and had a brief look at it with a mechanic and we concluded it didn't seem to be anything serious, we reckoned at a time that it was caused by a missing clip retaining my brake line and it was just banging against the bracket holding it in place (or maybe the exhaust banging against something). Since I'm going in for an MOT comming Thursday we desided to take a closer look then, but I figured I might take a closer look this weekend.

I already replaced the clip on the brake line but that hasn't fixed my problem so that wasn't it. The other thing I'm thinking about is that it might be my wheel aint properly tightened. I had this problem before on both my DeLorean and my AE that if you don't tighten the lugnuts correct or if the brake disk isn't flat against the hub when you tighten the lugnuts it will also make a banging sound on decelleration. But again that doesn't seem to be the case this time, allthough I haven't ruled it out because I haven't had access to a proper lift yet..

Any other suggestions what I should look at?? Thing is, this problem is not constant, I drove from home to Amersfoort and back which is about 150 to 200 km trip and I only heard the knocking sound 2ce in the trip. Really mistifying me. Freaking me out due to the damn MOT

(good news is that I figured my rear tires still have enough profile, not bad for 2 year old tires (shame on you Bas, not enough drifting done!) )
