My friend is trying to get a lsd into his 86 mighty max truck.

He is having a few issues right now. He found a 2wd montero sport without lsd, and a v6 raider with lsd. He pulled the punkin out of the raider and bolted it to the m.s. axle using ms axles. The only problem is that one axle sticks out about 1/4" while the other bolts in just fine. Anyone have any ideas? I'm guessing maybe the ms non lsd axles are a little longer?

I told him to go measure both and that may help, but I figure I would ask here as maybe someone has done something similar before.

This is probably gonna sound dumb, but if you were to just cut 1/4 inch from the shaft? what negative efects would you have? Would the shaft weakened?

A 4cyl LSD into a 4cyl open axle is a bolt up ..

A V6 LSD into a V6 open axle is 'not' a bolt in...

But... It can be done.. But it takes pulling the diff down .. Opening the LSD and cutting the ends of the axles and the LSD block... And 'buffing back' (cut) the axles where the splines meet the axle shaft..

Any Mitsu LSD needs a restacking of the plates really.. There very loose from the factory.. Very strong when the plates are stacked 'right'

The v6 axle is over kill anyhow ..Really ...Be nice to have the disc brakes of the sport axle .. I have a 4cyl LSD restacked if you need it..

well my buddy is about an 18 hour drive away lol.

If he can get away with just grinding the axle then that would be nice.

We built a stock 2.6 awhile back with a wideban tuned weber and he has been [censored] about not getting any traction in the wet so I told him to at least get a lsd. Only thing he could find in the local jyards were v6 stuff.

I have no idea if that driveshaft will even bolt to a montero diff

If it's not too late (sounds like it is) I have to wonder if it could have also been possible to swap the entire rear end into the MM?

I suspect this was a leaf sprung MM right? If so then the rear end from leaf sprung sport might have been the easier way to go and what i'd do if it's not too late.

You cant .. Its not about weak... Its about the placement of the axle splines to the side gears in the LSD ..And the placement of the axles to the lsd block.. The axles meet in the middle at the block.. The block and axles are hard.. So you cant cut the axle persay... You have to 'grind' them ..They have to be flat and smooth..With the right tools and brain speed it not hard ..

so to avoid grinding could he just take the raider v6 axles and stuff them into the ms axle?

No you cant... The Mitsu axle has "timkin bearings" on the axle shafts .. The axle ends meet in the LSD at the block.. load against the LSD block.. And you shim the ends .. The non-LSD axle wound not let you 'preloaded' the outer axle bearings ..I would think you could redneck it up (just add in your favorite racial slur here..Now make sure it reflects your own ethnic back ground..) and cut out a plate to fill the space and shim it up .. You cant just cut (grind) each axle either .. do to the block runs into the 'cross shaft' in the LSD.. If you do not Doll up the axle ends and block ends where they meet ..Right.. The axles will saw into the block ..And you well loose perload on the timken outer axle bearings..

Your mine set is right if the axle shafts had 'ball bearing' on the ends .. Ball bearings dont need and dont like reload..

timken is a brand of bearing. what typw of bearing are you talking about? ball, taper roller or?

'Taper roller and cup' in laymans terms..Sorry

A Mitsu axle is a full taper roller and cup (timken bearing.. Timken was the name of the guy who came up with it ..) axle assembly.. Thats why there so strong..
