I have an 86 4RNR and I would like to have a locker for my front and rear but I can't afford it right now. If I shim the spider gears to the point that they are almost too tight too move, will this give me posi front and rear while allowing slip for turning? I would rather not weld if I can help it. TIA

Why not weld? shimming the spiders would be as useless for off road as a posi is. A power trax lock right is an inexpensive alternitive.

I am not looking to off road this RNR, I mainly want straight line posi for our heavy snow conditions. How much is that locker you wrote of?

You dont want to weld or install a locker for a street truck. Maybe you could trade it in on an all wheel drive Subaru or something <IMG SRC="smilies/flipoff.gif" border="0">

This is my daily, my other Yota is away with a blowin tranny, I would install a locker if I could afford it. I am in my fourth year of college and money is kinda tight <IMG SRC="smilies/scary.gif" border="0"> . I need a solution that is cheap and will work. If i weld will I not chew off my front tires?

Posi/Limited Slips Differentials (LSD) units are around the same price as lockers. The cheapest locker out there is the lock-right at around $250... but LSD's are usually more than that - although I haven't looked for a LSD for a Toyota, so I could be wrong.

A posi/limited slip is just that - limits the slip between the two wheels on the axle, usually by using clutches which wear down over time - so it slips mor & more as it gets old. A locker permanently fixes the two wheels together, while still allowing one tire to turn FASTER than the driveline speed around corners, but never SLOWER than the speed of the driveline. Lockers are the ultimate in offroad traction, but perform poorly on pavement. Clicking, banging, and quirky handling are common with cheaper lockers such as the lockright.

The only option I would consider for a street vehicle is the limited slip. Lockers aren't designed to drive on pavement, although I have several friends who have been very happy with their Detroit (high-dollar indestructible locker) on pavement, and will soon be putting one in my rear axle myself.

Also, popular belief is that lockers can cause a vehicle to lose traction on ice & snow more easily, since when you spin your tires, BOTH front (or rear) tires spin, causing that end of the vehicle to shift sideways. I like to think that a locker may very well put your truck into a ditch in ice or snow, but you also stand a very good chance of being able to DRIVE of that ditch.

As far as your original question, I would expect that idea to wear out bearings or gears somewhere in the differential. Also, assuming nothing broke, you would find thosewashers worn down within a hundred miles, and all the metal shavings would be hanging around in the gear oil waiting to ruin bearings, gears, and seals.</font>

Shimming the spiders will not make it act like a posi (LSD).

Sorry its not cheap, but if you want a posi, then you'll have to put one in.

I agree with Beeb.

Secondly, If your not off roading anyway and just going for snow covered pavement, may I suggest some narrow, well-siped all terrains. My 33x10.50 BFG ATs kick ass on the ice and snow in the long interior Alaska winters.

If you still gotta get both tires turning save your pennies and get a tru-trac for your application.

Good luck and congrats on the 4 yrs of college.

If you want a cheap LSD for the front of your 86 runr than swap in one from a Toyota Supra. All together it cost me $160 CND or $100 US.

i have been running a "lockrite" all summer including commuting to work 40 miles each way on the freeway and city streets. while it ocasionally pops and bangs coming out of corners and slightly clicks while coasting through them. i find it completely managable on a daily driver and as long as you shift smoothly and coast through corners youll probably not even notice it. it is a wonderful, welcome addition to my truck as far as offroad performance goes...

i have heard and can imagine it doesnt provide a very stable footing(side to side motion) in snow/ice covered pavement when locked because you dont have that idling wheel to provide traction in that respect, so that could be something to strongly consider...unless you like sudden unexpected 180's and 360's in a lifted truck?? <IMG SRC="smilies/biggrin.gif" border="0">

why do you need a limited slip for winter? <IMG SRC="smilies/confused.gif" border="0">

just put it in 4 wheel drive. thats what it was made for. my axels are still stock because i still am in school and until i get out and can get a different daily driver the axels will not be locked.

if you are worried about locking you axel in the winter you might be a bit loco. but, each to his own. <IMG SRC="smilies/rolleyes.gif" border="0"> just weld the damn thing and be do with it. <IMG SRC="smilies/biggrin.gif" border="0">
