Mazda b4000 keeps breaking locking hubs autos and manuals

[Justafarmtoy]

I aquired the truck and have put some work into it. It's just a toy for now. It runs like a champ but can't seem to keep locking hubs on it I've broke multiple stock auto locking hubs. Multiple warn manual locking hubs and a few other brand internet hubs any suggestions as to why it does this and what Axel's are usually in these b4000. Thanks

Welcome to TRS

1994 can have a Dana 28 or a Dana 35, have a look here to ID yours: https://therangerstation.com/tech_library/dana_28_35.shtml

You may have failing axle u-joints

Is it just one side that breaks?

 

[Justafarmtoy]

Usually driver side have broke passenger side also. New u joints they have broke while in binds but have also broke just climbing muddy hills nothing super steep not driving hard just slow and steady and boom they disintegrate im gonna order some jeep warn and try them just stumped as to why so many different types have had the same outcome

I believe it's a d35 the truck is a beast and I've put quite a bit of time into it I'm determined to find some that will withstand so ky beatings so any suggestions are greatly appreciated

Maybe the previous owner swapped the rear end and didn't bother making sure the gears match?

I doubt it would move very far with different front and rear ratios, different size tires maybe

It doesn't break them quick just breaks them at random times some have made it a month or Better some a week or few days lol it is a Ford rear end for sure it's got the Same size tires all the way around new u joints gears in diff have been thoroughly inspected maybe just bad luck on faulty hubs or maybe something more too it majority of the time they break they aren't in a bind or anything I wouldn't think it's different ratios they don't fight each other it's pretty smooth that I can tell
