Stuck while changing rear bearing on my E46

Dear all, I need some help. I am new to this forum and I do not know where to start. I jacked up the e46 ci and I replaced the the rear left bearing. Straightforward I thought since I have changed all four bearings on my E39. One difference though. In the E46 Ci I had to remove the CV half axel from the diff in order to pass throught the bearing extractor. That was fine, no problem. Many videos on youtube directed me and so far so good. When everything was ready, I tried to insert the axle cv end to the bearing hub which I did but the threaded end just stopped sort from coming up the other end which meets the nut. Just short and it does not move. Please is anybody able to help me? Have I done anything wrong? Does the axle have a guide which I have overlooked and it stops short from meeting even the first thread of the nut? Please help the car is up and I am going away in a few days Please help

Take a wire brush and some WD40 and clean the splines on the axle. Then take a tooth brush or smaller brush and clean the splines inside the hub itself. Should make inserting the axle smooth as silk.

Dear smolck, thank very much for your replay. I have taking the axle out twice and all my body aches (I am not young anymore). To take the axle out requires a lot of effort. I am glad at least that I have not overlooked anything and I hope is only dirt I have to remove. I have cleanned it once but I do not think I did a good job. I will follow your instructions tomorrow and God help me. I realy appreciate your replay.

cheers
Dennis

Just an update. I cleanned the axle well with WD40 and brushed the hub after taking the axle completely out of the vehicle. Since I had the clearance from inside the hub I decided to use the the bearing tools to tighten up the already inserted hub (I had just knocked it with the hummer). To my surprise the hub moved easily a few more mm which unable me to fit the axle nicely and access the first mm of the tip. After that all was easy. I screw the nut and I was able to complete the job.

Cheers
