Front Differential Failures common?

Can everyone who has had the front differential fail (grinding, metal on metal sound associated with acceleration or deceleration) please comment? I think its time that Volkswagen come to terms with this defective part. It is notable that we are not seeing the same rate of failures on the rear differential even though mileage and wear is the same. How do they explain that?

Please sound off, maybe we can get a policy change established. My dealer says that if you push VWA they will own up to the problem and help to resolve the issue. We need more factual evidence that there is a consistent problem so please sound-off here if you've had this problem 2004-2010.

What were the symptoms?

How much did it cost?

Who did it for you?

diff bearings

Hi , repaired it myself i work on heavy plant , diff repairs are a common job , the bearings can be sourced for about 45.00 i used timken as fitted by zf when new , the bearings are used in bmw diffs as well , they are imperial bearings in the diff beware skf can supply a bearing with the same part numbers but they are metric part numbers in diff are KLM503310 seat KLM503349 bearing you will struggle to x ref the KLM number but K stands for imperial measured bearing , timken make an imperial LM 503310 LM 503349 which is the same part , bearings in the diff had slight wear but this caused side play in the diff , fitted new bearings original shims were spot on , i have added 1/4 liter extra oil to try and help the bearings survive , there is still a tiny noise from the diff which will be slight wear in the crown wheel and pinion due to free play in diff when it was run with the worn bearings , damage to the original bearings was lack of lube . diff was loud lifting of the throttle and just on the throttle , hard right hand bends made it growl

I had mine replaced at 108,000 miles....about 4,000 miles past the expiration of my extended warranty. Symptoms were constant whining that worsened over time. I put up with it for about 4 months. Cost was about 2900 + some labor to replace.

I do have the old front differential laying about if someone needs it to effect repairs on theirs....ie. rebuild mine, and then install it. PM if interested...

How often were the differential oils changed? Good to know there is an option to repair the otherwise expensive unit by using bearings alone.

It is bad enough to have to wonder about the valve chest going and the driveshaft bearing too. And then this revised 40K fluid change letter.

I have mentioned this before, but once again for some odd reason, other than Jimbuffalo, it is the 04 3.2 V6 owners reporting all the front diff failures on here.

170000km still on same front diff here, no symptoms yet. Replaced fluid a while back ago. I noticed the fluid darker than I would have liked, and therefore made the right move to replace that beat up fluid. The mechanic agreed as well.

Okay, a bit of mixup here. The 40K change interval is in the 09-11 owner's manual (V6 TDI). The letter is sent to disregard the 40K interval. Then there is a letter for all VW models equipped with the 09G Aisin-Werner 6-speed (TF-60N) to change at 40K miles instead of leaving it for the lifetime.
