Whine and Pinion Gear
#1
![Default](/forum/images/icons/icon1.gif)
The whine on my 01 S-type got worse. 1st take was it could be the VVT, and since they were doing something there already (mechs), I asked them to replace it. That did not do the job. Now that it is getting worse and I have to have the radio on, so I do not hear it as much, the diag is rear pinion gear. I do not mind replacing it, except I am quoted 2.3k. The reason being it is labour-intensive and will take 3-4 days. So, it's mostly labour costs. Is this reasonable, or should I look for a different mech? Thanks for any ideas.

Wait a minute… You thought it was VVT? That would indicate the whine was related to engine speed.
More info needed:
Does the whine directly correlate to engine revs?
Or does it directly correlate to road speed?
If it’s engine speed, suspect alternator bearings.
If it’s road speed, perhaps suspect dif.
Finding out which one is very important and could save you thousands.

thanks for this. there is no sound change turning. My jag specialist after stethoscoping the engine thought it could be the diff. We then went to the local diff specialist and it took him 10 secs to recognise the noise.
