Knocking noise - road speed related
Fix one problem and another appears.....
One the 'new' V70, it's just started developing a knocking noise that's road speed related and only audible below 40ish mph. Clutch in/out makes no difference. I've checked the hub bolts, both are tight. Can't seem to replicate it in the drive on axle stands. I've noticed there is more lateral movement in the offside drive shaft than on the car I'm selling, could this be a clue? Any suggestions on next port of call? Could a CV joint knock under normal driving, rather than on tight turns? Assume that after fixing the engine problems, it's now developing power/torque as it should and has stressed something on the transmission. Car is an '03 V70 D5 (manual) with 202k on it. |

Hi,
Two things I would check; First check for a stone or nail in the tyre. Next the ABS wheel sensor might be just clipping the toothed ring on the drive shaft. Good luck. bob

Might sound silly but I had that problem before and there was a stone stuck in the tyre thread.

and it's now refusing to do it, although only been round the block today. Hoping it was something silly that has cleared itself - time will tell.
Have noticed a slight knock (unrelated) coming on/off throttle, guessing a mount or 3 will be in need of inspecting. Was a definite and heavy knock that you could almost feel on the car floor - Hmm, scratches head! Last edited by reggit; Apr 16th, 2018 at 17:19. |
