Ive jacked the bike up and "swung" the swingarm as an assembly towards the rear enough to get the seal out. Used a ratchet strap to hold it back.

@PowerStroke70 has a 99 450 that shadetree is working on. Front diff is trashed. He wants to put a factory electric selectable front diff in from an 02-04 450, kinda like Retro and I did with the 400AT front diffs in our 350 Ranchers.

I know you just did the reverse on one of your bikes, removing the electric front diff and putting in the old style with a 424, so figure you'd be of assistance.

I have an extra 450 selectable front diff in the shop. If I send this to Shadetree is it going to bolt in place using the factory 02-04 front driveshaft? The driveshaft is the only bit question in doing this. I know the diff will bolt in place with a little trimming on the frame cross member to clear the actuator, and wiring it up using a Retro gizmo is easy enough, but I'm not sure about the driveshaft.
Well , I would think it would have to work , cause I took a 2000 450 full time diff and put it place of a 2002 electric engage 450 diff , I didn't use the OEM drive shaft , I used a Wide Open 4x2 kick-out for the 2000 450 , so that 4x2 is the same length as the 2000 drive shaft , so would my thoughts be theoretically or hypothetically , or just plan old coon-ass ciphering -----

LBZ has first shot at the 2002 diffs I got , IF , I were to ever sell them , he asked a long time ago --- I doubt I will ever go back to electric shift , it let me down at least 3 times back in the woods , I said before they should have made the default be engaged in 4wd , so when it malfunctions you are in 4wd

So leave the shocks hooked up and do a arched swing ------- Sounds like a plan

I been thinking about that leak , and come up with 3 or 4 scenerios , 1 - when I cleaned up the end of the shaft with chemicals I messed the seal up , 2 - the drive shaft is a bit long and has pressure pushing in on the shaft , 3 - the drive shaft is at too much an angle and putting side pressure on the seal , 4 - coincidence

I was thinking about the pin hole in the boot , could have been from welding the shock mounts , I had two fire blankets wrapped over the rear end and swing arm , but that boot would have been down hill at the end of the blanket ---- lucky it did have a hole to see a drip , I squeezed the boot this evening and there is no more oil in it , but would guess it only leaks when running , it would have filled the end of the swing arm with oil and the u-joint would have been submerged in oil as the rest of the swing arm tube is packed with grease

Seal and a new boot coming Monday , I had a couple of used boots , for $10 for a new boot , I want a new one ----

@SamUK swapped everything from his '04 450 frame onto a '99 frame. It looks like he just had to notch the frame the same as we do on the early Ranchers to fit the electro-diff & driveshaft?

i understand about the frame notching, what I need to know is, what/which drive shaft will need to go back in ?. me thinks it will need to be shorter, which means, the drive shaft will have to come out of a set-up from the original front diff set-up. this build I am doing has the full time front diff, its getting the electronic front diff, which tells me, the drive shaft has to be shorter.

Use the 2002-2004 drive shaft with the 2002-2004 electric front diff in the 98-2001 frame , the drive shaft are different lengths 98-2001 and 2002-2004 , the shorter one is 98-2001


this pic is two drive shafts which I " think " are the two in question , but not 100% sure as they were in the Shed of Doom and unmarked , one measures 11 and the other 12 1/2

That tells me exactly what we need to know. I'm sending a diff and 2wd/4wd switch to @shadetree in a few minutes, and have an 02-04 front driveshaft ordered from a guy on FB for $60 shipped (I didn't have a front driveshaft for a 450) so that and @retro's gizmo should be all Shade needs.

Thanks guys!

For comparison, this is an 05-11 500FM front driveshaft. I wondered if it might work, but according to Fish's measurements it's too long.

The 500 and 450 diffs looks like they will interchange (can't confirm it, but they looked the same, and the gears are definitely the same) but the front driveshaft is about 12 1/4" on the 500.

Just posting this here in case the question comes up again at some point in the future.
