    Driveshafts for AJM + DUK box - Avant

    Hi all, apologies if this is a repeat, my last post does not appear in the forum when I last checked.

    I'm wondering if anybody knows what the correct N/S driveshaft for an A4 Avant (sep 2000) with AJM engine and DUK gearbox. I thought it would be possible to interchange driveshafts from different models, like use part 8D0407451CX - however a quick search on vagcat(dot)com shows 8D0407451NX and 8D0407271EK... how do I know which of those is right? (yes I've googled quite a bit but don't have any answers!)

    I did also do a check through eurocarparts, but they don't even say whether the (I presume genuine due to price) shaft is NS/OS - or whether it is actually is the right one for my car... I'm presuming not to touch Q-drive with long stick. I should add that the reason I'm looking at replacing is because the inner bearings have fractured, so I was weighing up pros and cons of replacing inner CV section vs entire shaft... and here too I'm not sure if there are right and wrong inner CV kits!

    Thanks

    ETKA isnt any clearer, both those shafts are listed as Left hand side, tripodic, for AJM 5 speed.

    Looking thru ETKA, the AJM seems to use a unique outer joint , but the inner is shared with quite a few engines (mostly V6's)

    At a guess from the parts used, they've used the big V6 inner joint/shaft, and then the special outer CV takes the big shaft, and converts it to the small 75mm bearing. Most cars with the big shaft would have a big outer bearing, and thus a bigger (but common) outer CV.

    I suspect an Inner CV kit for a 2.8 FWD or 2.5TDI FWD would have the right parts. Or you could get a driveshaft from a FWD 2.8 or 2.5tdi and swap your existing outer CV onto it?

    Hi aragorn, thanks for your quick reply - that's certainly another option. Can you search according to chassis number on ETKA?

    Dealers can do VIN lookup.

    The shaft from Audi is £500 though!

    I wonder how accurate the autopartoo site is... it shows 3B0498201 as being right inner joint for most Avant models incl. 1.9TDi (115bhp) as well as the larger 2.8 FWD or 2.5TDI FWD mentioned above - just that it doesn't show AJM next to it in vagcat!

    3B0498201 is not the right part, thats a standard CV joint, not a tripodic one.

    The correct inner is sold complete with the shaft, part number: 8D0407417E

    Ah nice one... thanks, I found that mistake in my VAG hunting (snigger)... it looks like 4b0498201 is also the one? Been trying to get some info from local Audi garage but they seem to be rather busy! Either way it looks like I'd be better off with full driveshaft anyway...

    4b0498201 is the boot, not the joint.

    Thanks Aragorn, vagcat shows it as including joint, but like you say, google searching only shows it as a boot kit...

    Just heard back from a parts specialist... due to very rare engine and g/box combination the correct driveshaft is 8D0407451NX, nothing else will do... and it seems to be as abundant as rocking horse manure... and the inner joint kit is even less abundant! Main dealer it is... :/

    If it were me, i'd be buying a 2.8 shaft and upright

    Or, a 110hp 1.9TDI shaft with tripod inner, which will probably be a bit smaller/thinner, but will still fit.

    Not a chance in hell i'd be buying a new shaft at £500.

    Thanks, would you know the part number for the 110hp shaft?

    As said at beginning, I had wondered about this shaft here, but the seller says it won't fit...

    Finally got in touch with my local Audi garage, they say 381 incl VAT, not so terrible...

    Ok, some technical details.

    There are three different gearbox flanges on the b5 platform, 100mm, 108mm and 130mm (tripod).

    The 110hp diesels, your car, and the V6's all use the same 130mm gearbox flange when in FWD configuration.

    On the hub end there is two flanges, small one which takes 75mm bearing, and a large one which takes 82mm bearing.


    There are some typical combinations, for instance most (but not all) 4 cylinder cars have the 75mm outer bearing. All V6's have the 82mm bearing.

    petrol 4cyls tend to use the 100 or 108mm flange depending on wether its a 1.8T, or not. The 110hp/115hp diesels use the 130mm flange, as do all the V6's


    Your car is quirky, because it uses the heavier shaft designed for a V6, and thus is expecting to attach to an 82mm outer CV, but instead has a CV which takes the larger shaft and allows it to connect to the 75mm hub flange.


    The shaft you linked above from ebay is from a V6, thus it has a 130mm inner, and a 82mm style outer, and thus wont fit your car.


    A standard 1.9TDi shaft however will fit your car just fine, it will just have a slightly less beefy shaft.

    Part number is either 8D0407271CL or 8D0407451FX (i believe these are the same part, but the one ending in X is exchange)

    Mate, thanks again for the info. Do you have your own copy of ETKA?
