spool or welding rear diff
« on: Mar 25, 2010, 09:12:01 PM »
hey guys i have a question, i recently purchased a 99 superduty f250 5.4l v8 and i only have two wheels turning even in 4wd, the "ls" sucks, so what im wondering is if i should spool or weld my rear and front diffs, i almost never tow trailers or anything heavy this is just my new toy, i do drive it quite often and i want it to be able to do good on the highway, the biggest tire i'll run is a 35 bogger, i've ran a spool on my toyota and never had a problem but the ford guys are saying NO dont spool or weld, any tips?? thanks guys

I know this has been discussed in the past, I just don't have the time or energy to go looking for the thread.

Either spool or weld the rear, but I'd leave the front either open or put a selectable locker. Even a lunchbox locker would be OK in the front, but I would not weld/spool the front.

if your using it on a toyota i say spool its cheap i've used em in my toyotas and the spool has never broke, the gears will go before the spool is damaged. plus you dont have to worry about your welds breaking or wearing down and swimming around

you have a sterling 10.25 in the rear of that thing.... IF you do anything i would weld the spiders..... because eventually they will get pitted and howl anyway (i see at least one a month at my dealership) the two pinion carriers are way easier to weld but you can weld the three pinion, its just not as easy. or a mini spool, they are available (for the two pinion carrier) and you wouldnt have to reset the gears....

In a truck that big however i would consider a "real" locker....  We install alot of true trac's here and everyone seems to like them....
Those are some huge welds!
