Question

I picked up this pickup as my garden haulin', off-road hunting/firewood gathering 2-wheel drive vehicle. I've got some aggressive off-road tires mounted, and want to add a locked differential so I don't get stuck out on the backside of the moon. Suggestions?

    If all you want is a locked diff for off road only, weld the spider gears!! Google it and check youtube. NOW, suggest installing a limited slip from a salvage yard cause it just seems like the way to do it and many will tell you that.... but it's up to you!

    Weeellll...how would that affect road and highway driving? I was thinking of being able to switch between the two, IF the lock would negatively affect on-road performance. And guestimate about how much a used (lockable) rear end should cost?

    Changed your mind about on/off road + locked/lockable huh!!?!!!! You may have a limited slip in it now! Do both wheels spin if forced to do so? If you want a switchable air locker google it and shop prices, aint cheap!! I would rather have the limited slip and be done with it! Call a salvage dealer for a price if needed.

    Pushrod, I've looked it up on You Tube. There are a few videos that show how the spider gears can be welded together - that's a viable option. However, like you say, the truck MAY have the slip gear already in it - it was optional on that year of F150. Now all I have to do is convince my wife to stand behind the truck on the steep dirt hill behind our house, to see if both wheels engage when I spin 'em. ;-)

    That's cool, should be able to tell by just spinning tires then looking at the tracks.
