I have a stock '87 PU. What are best suggestions for putting a locker in the rear diff?
I don't have much in the truck, so please offer me advice on a budget. I've considered the ole' Lincoln Locker, but several folks told me I wouldn't be happy long term.
I drive the truck on the road about once a week to Wal*Mart and back, whether I need too or not. Otherwise it's sitting or running dirt.
Had one guy recommend an "Aussie" locker? Anybody got a link for that?

thax in advance

Thax

Thax for the advice folks. After talking, reading, & researching, I've pulled back from the Lincoln. I wasn't wanting to go the e.locker or air-locker...too much for my skill level.

However, after reading about this aussie locker, it looks doable w/ some help from the local shop. And, I like the "automatic" nature of the design.

thax again for the comments

Another rear diff question

Does anybody have experience w/ a 'mini-spool'?
A friend of my suggested I consider this option. He indicated the cost less than $100 and were very easy to install. He runs on in his '88 Toyota PU and talked like he had no problems even on blacktop, outside of some "cherping". No more road miles than my "fire-trail" truck gets, this is sounding like a viable option.

Thax for comments pro/con

Just as easy as instaling an Aissi locker, only NO disconect option so.........


If you dont mind the onroad maners a full spool is the best traction a locker is just one step down, when you turn you are to let off the gas this unlocks it so the turn is made unlocked the Ratchet sound, turn under power and its full spool.


*************************Certified Rant*************************



Off-road: locked, dirt, leaves, sand, snow.............allow the differences in the tire to be translated into sliping on the top surface.



On-road: LOCKED, the hard no slip, full traction surface does NOT allow the forces to escape, torque will follow to the weakest link imagine the output of youre motor at that time multipyed (x) by the gear reduction in the diffs. Tremendus forces are at work to tear the weak link, axles, spider pinion (Welded), splines, locker teeth................



On-road: locked, raining (snow, ice), the harsh way traction is applied, you lose traction with one wheel you do run the risk of torque "breaking" the traction wheel and............bye bye.


On-road: limited slip, wheels are alowed to softly apply traction. (in the "slip")


Off-road: limited slip, the tires are alowed to slip and in some cases (clutch type) the tractin wheel will be buried before the lock can be placed be the diff, youre stuck ;)


however in some precariously placed situations the soft aplication of traction is VERY needed, say wet off camber rock stalled with manuel trans, blah, blah........



this leads me to believe that some of the best mass produced 4WD's have either ALL GEAR limited slip's or selectable lockers.



My opinion, "IH8W8"

I also say no go on the lincoln lock. Go for the Aussie or I hear the Detroit EZ locker is good for the $220. I'll have one of those in the front at the recomendation of the shop thats building my third member so I'll tell ya how it is.

What ever you do, dont go with a Richmond/Powertrax Lockright.

What

If it's not a daily driver, lincoln lock it! :D


Size



i second the lincoln log.

just make sure you weld it reeeeeeealy thick.

i wouldnt go back on the one i logged. its one of my best mods!





Tires





Welding it on a street car is a no-no in my book. Buy a lunch box locker like the aussie-locker I`ve got. Wont set you back much either...



Do

You run, and what is youre driving style?


The only draw back is, depends on the HOW you weld it and the Quality of the weld usually WHEN they break it usualy means no diff, WHERE you are at that time is................................


Biger tire = weaker carrier


Bad weld = weaker carrier


Contaminated weld + weak = broke



I have seen P4WOR put the weld between the spider teeth so it still has MINIMAL slip
and in the event it breaks you can still get it home.

My truck is stock, except for the 100,000+ miles on the odometer. The tires are 235/75 - 15's, which makes them about 28" tall. My driving style is fairly conservative. I'm not into breaking stuff, did all that when I was younger, riding dirt bikes.
I bought the truck for $500 and it is used for trail riding, almost exclusively. I'll drive it to Wal*Mart once a week for a bottle of power steering fluid, maybe a run to the county line for "refreshments", otherwise, it's just off-road.
It's a low budget rig and will probably stay that way.
