    Just be very careful to not damage the leg. I would probably try to hold the upper body in a fixed way other than the chrome lower. Wood blocks are very useful as ram cushions. Phenolic pieces also work great, if available.
    Good luck.

    Wow, even using a heat gun, the shafts will not separate. I think Ken may be right and one of the bushings has somehow slid onto the other or something. I will be talking to the guy that does my snowmobile shocks and see what he thinks.

    At this point I think I better start shopping for a fork :x If it comes down to that, I saw a pair of 2005 front forks (from a 250R) going for 295 plus shipping. shipping would be $65 to me bc I'm in Canada. Thats $360, That sounds like a good deal to me, what do you guys think?

    The description says (the seller is moto-recyclers if you guys have heard of them)...

    In good condition. Straight.

    No nics, pitts, dinged or dented tubes.

    Seals are good shape. No leaks.

    Clickers are in good shape.

    Also, is there a difference between the 250R and 250X forks. And would '05 fork fit the '04. Is the mounting bracket for the brake the same throughout most of the CRF 250 years?

    Sorry for a ll the questions, I hope it doesn't come down to having to replace the fork, the cash flow is depleting quickly on this one . :?

    Dirtae, I just did my 2005 CRF and had a similar experience. I clamped the bottom at the axle support in my workbench vise (using leather strips to protect it from being marred) and used the outer tube like a slide hammer. The inner seal is the only thing holding the outer tube on at this point. Once you get aggressive sliding the outer tube out and hammering away at the seal you will notice that the low friction coating on the slider bushing and the wear ring will be peeled back. You will want to replace these when you reassemble your fork tube.

    Thanks for the info! I'm going to clamp it in a vice similar to what you did but add heat with a heat gun. Bc I've had it in the vice, and I've added heat, but haven't done both at the same time, I'm thinking it's going to work. I bought a pair of used ones that are in excellent shape for a good price. So I'm hoping I can rebuild mine once I separate the shaft and sell them to make the $ back.

    mrlassi, when you finally got the shafts separated was the guide bushing, washer, and seal still stuck in there place on the gold tube? Because thats my problem now :x

    I am going to try and get some pictures, because it is kind of funny. The bushing that goes onto the chrome tube (the slider bushing with the teflon coating on the outside) was actually sliding underneath the guide bushing (the larger one with the coating on the inside). actually had to use a press to separate the tubes. The chrome tube came out with the smaller bushing (teflon on outside) but everything else is in place on the gold tube haha.

    Anyone have any ideas on getting these out! I've tried a slide hammer, but the jaws can't get enough of a bite. I was going to try heat but had to get going. This has been the shock from hell
