Toyota Rearend. To Weld, Fozzy,or Spool?

I have a 1989 Toyota. I just rebuilt the bottom half of the motor. I just put a 3inch body, a 4 inch suspension. I am running 35s on it at the moment. I want to lock my rear end. I was thinking of having a shop weld it, then I got to reading does anyone have any ideas about the Fozzy? I might go with a spool but I will be driving on the road half the time. But I do a lot of trail riding so I want the extra traction. I do not have a lot of cash flow at this time. I dumped most my money in the Engine, lift , tires. Thanks

Welding the gears or a spool on the street is not a wise choice.

What is a Fozzy?

A Fozzy

a FOZZY is were you weld up the spider gears every two teeth, you fill the weld of two. you go all the way around like that. It alows for a little play. I have heard some good things like your truck will handle turns on the road a little better, but also the weld wears out of the gears..Just wondering if someone has done it before and had any input.

I dont think I would do that it kind of gives the spider gears a little momentum to break the gears or whole carrier and you are barely gonna get any play going around a corner before it posi's up and skids the tire around the corner anyway here are some pics of some good ways to do it

Weld

Thanks for the advice. I think im going to weld it for now. When I get the money Im going to with the dirty thirthy ( 30 Spline Chromalloy axels). Dont want to spend the money on a locker when im going to switch it out later.

That sounds like a recipe for a broken rear end. A welded rear is not as bad as people make it out to be, especially in an under-powered and over-tired toyota. If you up your tire pressure you'll hardly know it is there. The other benefit is that it is consistent, some of the auto-locker do strange things sometimes. But, if you're paying someone to weld it, you might be able to get a lunchbox locker for not much more.

i almost forgot that taller tires have less speed difference around corners....

sarcasm. tire size doesn't matter... unless tires are different sizes from one side to the other. and power makes a difference, but in this case he needs to worry about axles shearing and carier cracking... lot of stress created in a turn, and if the tires dont lose traction, something else will give.

Ok.

What I meant about the big tires was that usually toyotas with them on are pretty sluggish. You are right that it puts more strain on parts but I have had pretty good success with a welded rear, several rubicon trips without breaking it. Our "community spare" 3rd member is welded as well. I did switch to a detroit after awhile though for tire wear issues, welded is really rough on them. I honestly think that the welded rear had better on road manners than my detroit though, mostly because it is ALWAYS predictable.
