Beating off your knuckle joint

Recommended Posts

'11 700 Grizz here and I'm in the middle of disassembling one of my front knuckles to do a boot replace and I've most def reached a stopping point. So far I've got the caliper off as well as the 2 castle nuts for the knuckle and the 1 for the steering arm, but for the life of me I can't separate any of those joints the castle nuts were securing. I've beat on all of them using a big rubber mallet with no luck at all. Is there something else holding these joints together I haven't found maybe?

My next ideas are to try to detach the shock from the lower control arm so maybe that'll give way a little easier, as well as letting some PB blaster soak into the joints before pounding on them again. Thought I should ask on her first before using the PB though.

Last time I had to separate a joint like these was on my '96 Cherokee replacing one of my steering linkages. Had to get a special 2 prong fork tool to insert into the joint and pound away before it came apart. For some reason I don't think that'll be the answer for this one though.

I'm all ears.

You need 2 big hammers.

You use one hammer on one side holding tight on the knucke. Hit the other side of the knukle hard with the other hammer.

Should pop em right off.

Thanks LT. I've read a couple suggestions to use two hammers but I just couldn't visualize the technique so in the end I opted for a tool from Harbor Freight called a ball joint separator I think. Worked like a charm.

      My Stable is LEAN these days. You will be happy to know that I bought a Quad in 08. A Raptor 700R. I put a weekend on it and it has been parked ever since. Worst purchase Ive ever made!!! My Yamaha shop even tried to talk me out of it.. About 8 Hrs total. My son wont let me sell it as he wants it in a few yrs. LOL..I still have one Trike. My trusty Tri-Z. I havent ridden it since 07? Just bought a 2014 RZR 800s a few months ago. With AGE comes a CAGE is a very true statement. I will enjoy this until I retire in a few yrs then get a bigger one!!!

      Signal Hill, CA (December 1, 2008) PCI Race Radios, the leading supplier of Communications to the Powersports Industry has acquired The Solder Joint, of Orange, California.
