Unusual noise


Recommended Posts

Hi Folks, 03 90TD5xs 54,000 miles. Had this problem quite a while but only ever happened when weather around freezing. Occasionally when pulling away and reaching first corner the vehicle would emit a sound not unfamiliar to a flock of gees for a few short bursts. then every thing fine after. Trying to emulate never produces anything (bit like going to dentist, toothache disappears). drives, brakes and handles fine, so have put up with this on and off. Until the last few weeks when the noises are happening every journey (and it's not cold) some times very loud for short bursts, or just the occasional quiet honk.

Anyway yesterday jacked the 90 up on axle stands and a spun the wheels, normal spin for a few turns then stopped, tried moving top and bottom for any play, no problems. got son to start up and put into gear and drive with me checking under to trace any noise, worked through gears Hi and Low and also with diff lock on, No noises,tried holding individual wheels when in 1st, wheel held other 3 turned ok, worked away around them all still no joy, then stood back and walked around as my son went through the gears again and then noticed front nearside wheel not turning but other 3 were. Brakes on then started through the gears again, changing gears moves the wheel for a few turns then it just stops, each gear change moves the wheel then it just stops again. I can spin the wheel OK, there is a bit more drag than the rest but not enough to stop the wheel under drive (or so I thought). Can anyone shed any light on where to start. Sorry for being long winded,but hope I have described it fully. Just a thought my ABS and Traction control lights are on (Nanocom says sticking shuttle valve) not sure if this would affect anything also had new pads all round last service, less than 6,000 ago.

Look forward to your thoughts.

Regards

Dennis

Thanks for replies. Apart from taking it all apart (which may be next job), can't hear any noises at all on full lock in Hi or Low box. No play in wheels or steering, drives fine in a straight line with no pulling at all to the left (thought maybe brakes sticking or traction control stopping that wheel slightly).

Any other thoughts before dismantling it all?

Regards

Dennis

I had a similar noise on my 90TD5 - I always described it as "mooing". It always happened at low speed, typically in the first half-mile of starting off in the morning. Cold/damp weather made it worse!

The noise was related to the rotation of the wheels. I discovered that it could be prevented by rocking the steering wheel from side to side quite vigorously while travelling at low speed.

Turned out to be a 'tight' brake caliper on the rear - identified by very light surface-rust on the inner face of the disc (hidden by the splash-shield).

Two new rear brake calipers, new discs and pads solved the problem.
