Well i got my diff professionally welded by my buddy Josh Napoli of J&K Machine shop today to my specs, and since it was the PROPER way or at least PROCESS of prep cleaning and welding, i figured since i was having it done right, I'd take pics and maybe show the new guys how to clean/weld their diffs my way, as well as many others.
I'll keep this short and to the point with pics and captions, sorry for the lower quality but i didn't think I'd do a write up and was just using my cell.
Step 1. Clean your Diff. let it drain completely, if you're in your garage, use brake parts cleaner (the kind that doubles as a flame throwing spider killer), and thoroughly clean the spider gears, and as much of the inner housing as possible. as shown, it's in a parts washer.
Clean on the inside clean on the outside, clean on the inside clean on the....
finish it up with brake parts cleaner (make sure to hit both sides thoroughly)
in my case, i chose to run with gusset plates for added insurance.
bing bing, one on right was trimmed after this photo.
Step 3. SECURE THE DIFF!!
also secure the ring set as shown, tack weld the top of each spider gear on both sides, make sure tack, turn, tack turn, or you'll overheat the bearings.
Step 3. WELD!
usually you can just fill in the ring set, but as shown, i chose to run gussets, you can see the fill around it, do so similar without the gussets, weld, turn, weld, turn
Allow cool down as necessary, i chose to let it cool with the all the filler, so while it did, i got to ride this sketchy bitch for about 45 minutes....
Why Bar Stool?.................... Because Racecar.
then, throw in 2.5 quarts of the cheapest 75w90 you can find, install it and rape face (on the track).
Once again, thanks go out to Josh Napoli of J&K Machine shop, they do full machine work and are top quality, also to my girlfriend for putting up with me and my "drift car".
Fin.
