imwant to install my 3.73 but there is one thing that is keeping me from doin it, and it isthat i have open diffs. i know the best thing to do is to buy a limited slip or locker but i cant afford that. i work with a few welders and was thinking of having onethem weld my rear end so that its always locked. i know the pros of having it welded is a fully locked diff but i dont know the cons of a welded rear end as to if i where toinstall a limit slip, locker, or leave it open

Not a good idea especially if it's a street car but if you want straight posi just buy a spool.
If she's a daily driver you should save up and buy a good limited slip posi.
Dragging a tire around corners all the time you car will corner like crap and wear out tires.

No PRO has a welded diff, Its an old dirt track thing. You ever watch a dirt track race? Those tires are spining almost the whole way thur the turns. I have seen some very low budget drag guys do it but it make moving the car around on the asphalt very tuff. Simple fact is when you go around a corner the tires travel at different speeds. Picture a car turning a sharp right hand turn The right rear tire may turn 2 revolutions in that same time the left wheel may need to turn 6 revs. With a welded diff you would either twist offan axle or the car would rabbit up in the air and hop around the corner. I have seen cars with welded diff try to do a u-turn on asphalt, aint nothing pretty about it.

yeah thats what i thought would happen in a sharp turn one tire would travel further and at a different speed a welded rear end would not allow the tires to turn independently where as the the limit slip would but would still hook under heavy acceleration. correct?
It is a DD and its mostly city driving so i take a good bit of sharp turns.

thats what i was gonna do but the guys at the welding shop said it would be okay and i tried arguing my point on why it wouldnt be good, but i had no luck so i decided to see what yall would think and i got what i expected, so i guess ill keep saving andthanks for the quick responses

right now tire slippage is not a problem cause i have stock 3.08 gearing so it not a big deal. but when i put in the 3.73 i think i might have a little traction problem so i figured i would most likely need it with the new gears

Maybe I'm wrong, but even with the new gears, I don't see your car as being one that will have a "sit & spin" problem. At least not unless you're brake-torquing it. Yeah, you may break em free a little easier, but is it really worth the expense to install an LSD?
