New noise from the front.
Its a 2002 KV6 ZTT automatic with 116,000 miles on the clock.
A new noise from the front has appeared which I can best describe as an irregular muffled clonking sound which only appears on the over-run. Has anybody any thoughts on what it might be ? Thanks, Malc Last edited by chicochapman; 19th June 2022 at 10:42.. Reason: added automatic |

At 116,000 miles has your ancillary belt tensioner ever been renewed?
You could also examine your engine mountings. Simon

Thanks Simon.
I have an invoice from MG Rover Mobile Mechanics of Derby dated 2015 showing "all cambelts, cambelt tensioners, guiders and waterpump" were replaced at 87,000 miles. On reflection, I think the noise is there all the time - its just more apparent on the over-run when the engine is quieter.(my hearing is not too good !) The lower engine mount was replaced about 2 years ago as I noticed a distinct "clunk" on moving off, however, I'll have a look at the other mountings as you suggest. I'm also thinking of waggling the front wheels to see if its a bearing problem? Thanks, Malc |

Hi Malcolm,
It was the ancillary belt tensioner I was asking about! From memory, if you remove the OSF wheel arch liner you can observe it whilst an assistant revs the engine. I once did this on a friend's Saab 9000 and the loss of belt tension was very apparent. Simon

The large bearing housing that transmits the drive shaft to the offside front wheel , have for some members been an issue once they get worn and show signs of play. They can be replaced . You could check that out once you have eliminated the other suggestions first.

Solved
Well, I'm embarrassed to admit it but in the interests of full disclosure,
it was an insecure front wheel! Four of the studs showed a wide shiny area where they had been "fretting". I just used the hand wrench to tighten the studs on the basis that in the event of a puncture I would have a chance of getting them undone. However, all tightened to 125 now and I'm keeping the torque wrench in the car. I'll get me coat! |

It's nice to have an inexpensive and satisfactory solution Malcolm! Thanks for reporting back.
