VLSD install help! - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Ok, so my 90 240sx has an open diff no suprise. I bought a 1993 240sx parts car (smashed roof) that has an immaculate working VLSD. I know you can simply swap them, but does anyone know any links on a step by step. I used search and no luck as well as google. All i get is how to change your diff to j30 etc. I am new at this so just a simple tutorial on how to replace a diff would be great. Thanks

You just use the FSM and unbolt the diff on both cars. Install the entire pumpkin over to the single cam. It's just a stock replacement.

FSM? Factory Service Manual? so do i pull the gear casing off the driveshaft, pull the diff pumpkin out and swap them? simple as that?

Since you have the entire car it's nice. Everything from the where the diff meets the propeller shaft to where the diff meets thedriveshafts can come out.

You should not need to swap over the driveshafts and should be able to reuse your existing driveshafts on the shell, but if you find that your VLSD doesn't line up with your driveshafts, you can swap over the entire driveshafts from the donor.

Also depending if the VLSD has ABS or not, you may or may not need to work the propeller shaft to fit. If the stock propeller shaft doesn't fit, call DriveShaft Shop for a 1piece.

TIP: change your diff fluid with the diff out of the car. Much easier.

Swap the drain plug on the gearbox on the donor with the filler plug on the diff on the shell.

Thats what he was saying. You dont need to open the dif at all. Swap the whole shebang into your car.
