I just bought a 2006 250ex for my son for 1800 because it has a bent axle. I have the new axle on order and am wondering how hard is it to change and do the seals need to be replaced and if so which ones. Thank you for any help.

 

Don't know about the seals on the 250ex, but yes, since you have the axle out, would be a good idea to replace them.

 

What was the cost of the axle? I am interested in buying a 02 for 800 but it has a bent axle. If you have the part# that would be great...

 

you can get after market axles for 120.00 Brand new on ebay ..

if theres any play in the axle with it tight
. get a berring and seal kit after you get it apart and see what u have the stock berrings are about 12mm (7/16")wide..and double row berrings are double wide
if theres no play your fine with the old berrings

my 250x has stock size and my 300ex has a lonestar carrier with double row berrings



as for removal ..remove the pin and nut holding the right wheel hub on ,then remove the hub and the rear brake calaper..then the jam nut needs to be fully loosened (I used a pair of pipe wrenches )!! the jam nut has left hand threads!!
with the jam nut loose it will expose a ring that you can get off with some skill and a couple of screw drivers

with the ring removed the jam nut should slide off ,,next the rear brake hub should slide off

now if your chain is off the axle should pull out of the left side of the carrier
ive never had to remove the sproket hub ,but if your new axle dosn't come with one you'll probally need to.and i belive it goes off toward the right end of the axle.

(sorry I posted about a 250x or 300ex the 250ex is shaft driven prob a little different but pretty much the same when i repalced the axle on my 300fw exept the axle jam nuts were diffrent......

 

the sprocket hub will never come off
