a4 01e swap

[marka4]

Hi there would you be able to help me on axel issue with 01e swap in my b5 please I thought I had s4 ones but thay dont fit. They may be a6 shafts :(
Do you have a measurement of the correct axle?

I have read about swapping the rear 01a diff cups around but wont that have cv strength issues,

I have swapped the uprights to alloy b6 units witch have the larger cv spline so if I swapp the cups sround id have to get new axls anyway as the axle spline is small for the outer cv? Inless you can get small axle spline to big upright spline haha hmmm please if any one can help thanks

Shafts i have are to long

Running the 100mm CV cups with your stock driveshafts won't be an issue strength wise, unless you're making 450whp / 500Nm, and launching regularly.

I don't know what the B5 S4 driveshaft lengths are, but I can dig up the part numbers.

Bear in mind, the B6 aluminium uprights have the bearing offset in relation to the carrier. They are set lower down, meaning the front of your car will likely be higher than the rear.

What spec is your motor? V6 or 1.8T? If it's a 1.8T, what sort of power is it making?

Thank you for replying. I have been puting in a aaa vr6 engine with a bw s366.

Issam has made me v nice engine mounts, I have coilovers so play around with hight issues.
But if I change over the rear diff 01a cups use my original shafts I run into the cv splines being different size can you get ones to work like the v6 ones??

Ok so I have bought new cv today with small spline axle to big spline hub.

My only issue now is the abs sensor hits the trigger wheel and doesn't sit center of the sensor hole in upright.

I was thinking of adding a washer to bring it back 2mm b sweeet. But I gess ill have to wate and test that out later.

Ill have a look on line with how to swap out the gearbox and diff cups. In less anyone know how :)

The gearbox output flanges are easy to swap. Just make sure you pull one at a time. Removing both may cause the crownwheel to drop in the differential housing, making it harder to insert the replacement flanges.

I would advise you replace the seals at the same time, and use new bolts.

The stock front a4 1.8t axles hold just fine even at over 600awhp, even held up just fine on a launch while I was pushing 47psi at over 700awhp. Now running them with my fully rebuilt 01E I swapped in.

Haha yesss thats what I like to hear. Aww dam I was excited I had seen pictures on how to do it and pulled out dam.
This is my afternoon job swap new cv onto old axle and insert :) need wheels if I put my calipers on though my old ones r to small
My seals seem in good condition still soft. ill risk it this time but it really isnt hard this swap hay lol just heavy (without lifting tools) just me my m8 And jack lol

[Aragorn]

Use S4 shafts. Streight fit if you've fitted B6 uprights (or v6 spec/big bearing A4 uprights)

[marka4]

I wish I could. I honestly thought I had s4 shafts, But I cant find any I have asked the whole of New Zealand no 1 has any. So new ones from dealer errrm no thats expensive hay wow then 034 ones but geez and postage ontop I could buy a na audi a4 not a tidy 1 but could buy a car here lol. Ill try this with my old axels and save money.

I can put that towards my center shaft any 1 have idears on wether it should hqve the cv ends or solid??

Ok I have found an issue with swapping over the gearbox flanges. The rear diff flanges fit but dont seem to seat fully like the original 01e box flanges.

Its slightly longer in both parts on the flange is 3mm shorter do you think I should try n take that off with a lathe or will it be ok??

Also there is a bit of play like 3mm once the bolt is done up. I have keped the bolts with the flanges

Hmmmm what you think guys/girls

Correct the rear diff flanges will not sit all the way in like the 01E flanges they are replacing. You do not need to modify anything, it will work the way it is. The stock axles will bolt up just like they did with the stock transmission.

Iv been told not to do this swap because of the moovment issues so im trying hard to find a pair b4 going to dealers.

Woulnt water n dirt get on the part between the seal and flange?? It looks like it seals but it all seems to risky

There isn't going to be any flange movement once you have the axles bolted in place and it isn't like the flange can pull out. Once the axles is in place the flange will be pushed in as far as it can go so there shouldn't be any issues with the seal. Others have been running it this way for years.

Aw well now im really unshure, i have everything sitting on the floor ready to build up my old axls and im good to go but this g box was so hard n expencive to find if anything was to go rong my wife will kill me n sell the car lol i wont let her but would you cut down the flange bolt to stop from mooving pice of mind or put washers behind it? What have you done m hood ur the man

You really shouldn't worry about it, just run them the way they are. I am not worried about it at all on my car and my 01E swap cost me around $4k by the time I was done with it. lol

Yay I have solved the flange issue vw t4 euro van have the inner cv joints to do the 01e swap on 99 a4 b5 axles

Im hoping now thay sell them here in nz, you can do the outer cv swap eazily using audi cv joints small spline to big hub sorry cant remember the sizes
