2.8JDT Gearbox Whine

Hi,

My 244 has done about 80 thousand miles. Now getting what I think is a gearbox whine. I don't think it's a bearing as I've checked. Also it's now starting to make a noise on overrun even when clutch dipped.

Can't see one left than 100 on ebay of joy and thinking it may be safer to remove and re-condition myself :/

Any suggestions anyone?

Ulp

Re: 2.8JDT Gearbox Whine

I'm not sure how you can check for worn bearings without removing the box and moving the first motion shaft around, even then layshaft bearings cannot be checked that way. Whine in either drive or overrun is usually caused by the gears being slightly out of mesh, and this is caused by wear in the bearings as a rule. Strip the gearbox carefully trying to keep together the gear clusters, and replace any bearings showing even the slightest play of roughness. Get the right bearing grades, 0,00, or 000.

80,000 miles doesn't seem much for a gearbox to start whining, but these Fiat boxes were not well made nor well designed.
