    Hi everyone,

    My rear diff cover is leaking and I have to replace it. Just wondering if there’s anything I should know going into this. Gonna take a grinder to it then weld the new cover on, I don’t see any other better way to do it. I’m planning on replacing it with this:https://www.barnes4wd.com/Toyota-T1...ndra-Heavy-Duty-Differential-Cover_p_359.html

    I read a post where somebody recommended against using synthetic fluid, does anyone know about this?

    Thanks

    If you have a factory LSD synthetic fluid will cause chatter even with friction modifier. If you have a open diff you can run whatever you desire.


    For the LSD diffs Lucas severe duty seems to be the best for our LSD clutches

    As much as I hate dorman I would recommend their diff cover over the Barnes unit too. The Barnes is ok, but the dorman is factory shaped. The shape of the cover helps with the oiling of the ring gear and pinion. Diff temps likely will be higher which leads to more wear with the Barnes cover. The punch out on the factory and dorman ones guide the fluid to sling over the ring gear and in effect the pinion

    Replaced the entire rear axle (swapped out the shafts as the the brakes were junk) about 8 years ago. Only extra parts needed were new u-bolts, some brake fluid, and POR-15 with paint.

    There's lots of parts already out there so it may be easier that welding on a new cover.

    Thanks for the input. Is this the cover you’re talking about?
