Hey guys, gals? new here to the site. ,I recently purchased a 1992 Landcruiser with 215k. Love it truly and have spent a lot of time cleaning and very little driving. After pressure washing I discovered both brake lines to calipers were leaking. so after several quotes I decided I spring for the parts to do a complete brake job and do the work myself. New lines, calipers, cylinders, pads, rotors, drums..you get it. Oh bearings too. Mind you I'm not a mechanic but am armed with 92 service manual Toyota graciously had printed for me and have also watched so many videos, read I feel like I could do the job in my sleep. UNTIL!! #1. I noticed irregular wear drivers side spindle. Fine called Fj Parts and he says their are two types of spindle s and I would have to remove mine to know which I had. No problem except! #2. I remove the first bolt and what looks like tan kind of foamy oil starts pouring out. Dif fluid I assume but this is were I come up short in the knowledge department and am not really sure how to approach it. Is there a bigger problem? Any help would surly be appreciated and thanks for all you have already done for me.
