Default C5 Avant: Axle Stuck to Transmission

I decided to replace my passenger side axel due to a torn CV boot. I removed all of the bolts and actually got the hub end out of the spline but can't get it to clear the hub. When I replaced these on a MKIV GTI and a B5.5 Passat, I was able to pull the transmission end free first. However, on my A6 Avant (Auto Tranny) I can't get the transmission end to release. I have removed 6 bolts and the 3 heat shield bolts. Am I missing something?

I'm thinking that removing the tranmission end will give me enough clearance to remove the axel without messing with the pinch bolt (mine is mega seized).

I've tugged and tugged on this sucker and the axle flange is still matted to the tranny flange. I'm stumped

Thanks,

Andy

I just performed exactly what you are doing. I replaced both outer CV boots on the front axles. You will have to remove the pinch bolt or remove other ball joints so you can get the correct clearance required to remove the axle assembly.

I'm working on the pinch bolt. Going to try some heat this weekend. If not, maybe I can turn the wheel so that I can get my impact on the back of the bolt.

Just undo the two bottom control arms.

My pinch bolt is fubar and will have to be drilled out at some point. The threads are damaged that I couldnt even get a nut back on the bolt.

In the end though, I'd the transaxle side wasn't corroded and seized to the tranny, I think I would have had enough play to get out the passenger front axle without involving everything.

No idea why most DIY's point out the pinch bolt for removal...unbolting the lower control arms is relatively painless and generally much, much quicker.
