Weldinmg the diff

I cant afford to get a posi so I am seriously considering getting the diff welded. I want to be able to smoke both rear tires when I dump the clutch or power brake. I know some will think thats stupid, But I love to see tire smoke. Some off road some do other things. ANyways, Will I regret it afterwards. I cant afford the lockers or a rearend swap right now. MAybe down the road. I would like to here from those who have done this or know someone who did and what all was encountered

Yes, you probably will regret it. You'll wear out your tires amazingly fast, squeal through just about every turn, and have massive handing problems during high speed maneuvering.

In addition, if you just weld the diff, sometimes they break, or the axles do. I really think on an older Ranger that is street driven, you should just wait until you can afford to do it right.

Just for the heck of it, I put my locker on and tried to do normal street driving. I don't like it -- it's something you wouldn't do for a street driven truck PARTICULARLY if you need handling ability and not just straight-ahead traction.

dont do it. not for the street. not if its EVER going to be driven on the street. i bought a spool once for the torino and changed my mind, sent it back and bought a rebuilt POSI. the spool was 30 and the posi was 450, but with a spool, you could damage the tires axle shaft and driveshaft. maybe for a drag car or demo derby car, not for a car you like

On an '88 I would think most likely a 7.5.

weld it up... you can be the example we go back to, when we need to tell people in the future why you shouldn't weld your gears...

keep a camera on you, so you can document the after effect, when you take a corner in a light drizzle. many telephone poles in your area?

I'm with Griggs ( on driving with the rear locked ) . There are times when doing a ' 1 wheel peel ' is a good thing.

Save your funds and look in boneyards. Theres a bunch of 7.5's in 4 or 6 cyl stangs as well as earlier rangers. You could probably pick up a diff for less then 100$ Its cheaper then braking your axles and winding up where your presently at anyway.

A spool would still leave you with the same problems driving on the street as welding the spider gears.

Except it might be less likely to break (though the axles still can).

I saw something on another forum, I think it was generation edge, but they added in something to the rear end that gave it posative traction. I do not know much about engines, transmissions, and other mechanical parts. Just thought it might help.

Spool or welding on the street is asking for death in the rain. Spools are for off-road use only!

Welding a differntal is the best bang for the buck. BUT it needs to be done right or else the gears will break and...well ur fawked. since this is going to be a pavement pounder id look into, like suggested before, a OEM limited slip carrier. rebuild it with an 8 clutch pack and heavier Z spring and it'll perform like a locker because the limited slip will be very tight. add some good gear erl and LSD additive and go to town.

other options are a power trax locker that'll drop in the carrier in about 2 hrs and will effectivy lock both tires together but "allow" for slippage when u let off the gas.
