rearend question
i've been dreaming of having a limited slip rearend in my van for some time now, and today i was walking the junkyard and found an 89 e350 with axle code c2, which my research says is a 4.10 limited slip. would it be possible/reasonable to take that LSD and install it in my 87 with axle code 33 (3.54 open)? since both are dana 60s, i would guess thats reasonable, but want to be a little more sure before i invest money into it.
thanks--josh
edit: to clarify, i'm talking about putting that diff in my axle, as i don't want to change from 3.54 to 4.10 gears. i just read my post and realized that wasn't clear

What kind of lsd is it, and how much do they want?
These appear to be clutch-type lsd units, but you'll have to wade through what will fit with your gears.

why don't you just go out and buy a lockrite or whatever is available for your axle. it just goes in where you sidegears/spiders and shaft go. do an oil change on it while you are in there and no changing shims or anything. if you don't like it pull it out again and sell it. only a couple hours work on a weekend.

NO, 3.54 gears are small carrier, the 4.10 is larger, if it was a 3.73 you could use it. This is my nightmare, my 99 has 3.55 gears and I want 4.10's, I used to off road a lot, got familiar with this problem. ^^Go with a lockrite or other lunchbox locker that pops in the carrier without requiring removal for installation.

thats good to know, thank you!
i'm not sure that a full-time locker is a good choice for a mostly-highway vehicle that plans to deal with some snow this (and every) winter. over half of my drive time will be on wet pavement (this is seattle, the land of rain and coffee), so i don't think that a full-time locker that forces one wheel to slip every time i go around a corner would be a good idea. if i were using the van for more serious off-roading, i would consider a full-time locker, with a part time unit being preferable, but i don't think it fitting for my use.
what do you guys think?

i'm taking time to read up on them now, i was under the impression we were talking about a crude "spool" which would be equal to welding the spiders, and not suitable for a street rig. now that i've read a little about them, that sounds like a reasonable option to look into.
thanks for all the input guys!

Lock Right makes 2 styles of lunchbox units, one is more oriented toward the street. That's what I would go with next time.
I went through the trouble and expense of getting a factory Trac Loc installed. It does work but I sure paid for it.

and the factory trac lock units don't stand up to any kind of offroading, good for street use only
. Great for some snow and loose surfaces towing at least.

Nothing from any manufacture is suitable for heavy off road use because they are destructive on the street, face 9it, people buy such vehicles for statements, and the toughest terrain they face are curbs in parking lots. True lockers will ruin tires on the road because they are designed to lock, slippage is at a minimum, not enough to cut out wear. Chevy had one in their 90's trucks, owners complained because they made a ratcheting noise in the turns, bothered the yuppies, causing the discontinuation, look at the H2-3 Hummer. For both you need either electric or air locking devices, allowing you to run open until needed, but they are costly and installation is complicated, requiring additional parts that are susceptible to failure.
Anyone who has operated a military vehicle made by auto manufactures, they'd tell you the ride on the street was poor, yet off the pavement was nothing like vehicles off the lot.

I remember a detroit locker available in a F450s up to at least 95, I roadtested it when a customer complained about the noise.
my offroad truck had detroit lockers front and rear and 38" swampers, only time I heard anything on the road was going around corners, or really hard on the throttle it hard a little torq steer.
ah swampers...............fond memories back when gas was half todays prices

I recall when my front was locked in my 78 F-150, right turns were easy and sweet, a left would rip the wheel from your hand or tear your thumbs off, yuppies hate it, so today's change in mostly open front. It's difficult to find an operating unit in a used axle due to lack of care, gear oil changes, or lack of destroyed them quick.

Well, my adventures can best be described as off pavement, not off road. The Trac Loc does just fine for that and its a 2WD so anything more serious is done slowly. Besides, I'm not taking a 3 year old family-do it all vehicle into the bush and thrashing it.
But here is an interesting thing. Mine has 32 spline axles and there is very little available unless you want to change axles too. All I found was the Lock Right, Trac Loc and ARB. The local gear shop offered to build me a Power Lock out of a Dodge Dana 70, but I already had my Trac Loc by then.

Great advice here , my limited slip carrier , from a 73 F250 , ended up costing around $600 to set up by the time I bought the bearing kit and had an axle built to match the carrier and take up the extra length of the van housing .
I must say , however , that is the single most beneficial mod that I have made . My driveway is steep and pitted in places and it is really nice to ease up the driveway with a couple tons of dirt in a trailer and hear tires start to scratch , then hook up without losing momentum or digging more ruts .
