DIY: Removing and Welding the Rear Differential
1- Jack up the rear end of the car. Follow safety guidelines for jacking up the car because you'll be way under this thing and getting rough with it at times.Also drain the fluid at this point which (I forgot to until it was down... whatever
2- Remove the axle shaft bolts first, 6 per side (Green)
3- Remove the Drive shaft bolts next, 4 total (Pink)
4- Remove Subframe Differential mounting Bolts, 2 (Blue)
5- Place car jack under differential and support weight
6- Remove Chassis Differential mounting bolts,2 (Red)
7- Drop the differential by lowering the jack. This is harder than it sounds. Getting the axle shafts to seperate is tough because they have a large nipple (lol) that goes in to the differential. There are ways of getting it done but there's no one way, so advice is great but in the end.... just get it done.
8- Slide out the Differential and Remove the Cover bolts
9- Clean it out with Brake Cleaner. Make sure to spin the center housing to clean BOTH sides because you will weld both side. (You can only spin the center if both shafts move the same direction We'll make that stop soon!
10- Once it's clean weld the Spider Gears to each other. (They are the four gears in the very middle)
Start in the corners, also weld up the edges to the outer wall.I only got one pic of this by accident, sorry. I meant to take a lot more but this was the very first pass getting into the corners.
11- Once you're satisfied and it's cooled down try and clean out some splatter (It's inevitable imo).
12- Using a small amount of liquid gasket install the cover. Replace the fluid. Put the dang thing back up under there... again easier said than done but you'll be fine.
RESULTS: OK so I started to upll out of the garage slowly... I turned the music off, windows rolled down... The slightest turning WILL cause squealing, hopping etc... A small drive down the street showed a car with totally different characteristics. It will drift sideways with absolute ease! Imagine being in second gear rolling at 25, cranking left and flooring it and the thing will absolutely fly... hehehe very fun. My Launch jumped by 1500 RPMs (Up to 2500) and with sider tires and traction control I am sure it would make a good launch upwards of 4K.
Anyway... So I took it into a local school parking lot and even at night I was invisioning trying to drive this everyday if I worked in a city with lots of parking lots and short roads etc... Ehhh Your call but let me state my opinion on this::::::This is not going to be a good choice if you drive this car every day to work, store, church, pick up kids etc... LUCKILY for ME I have an I30 and G20 that I will be now using more frequently.
The performance characteristics are GREAT! but the daily drivability is just a little over the top and imo you'd be better off buying an LSD of some sort.
