if it was simple enough everyone would know how to do it and would always do it properly the first time. It can be very frustrating sometimes and you have to break down the diff every change u make and re assemble it all back together to check your backlash again..

Like I said, your supposed to shim it. however, many people do not and many have completely trouble free operation.

Also problems with the Nissan R200 rear differential and a welded differential is that it can take out the pinion shaft. It will loosen it leading to numerous problems... leakage, pinion seal, pinion bearing.. if it gets bad enough it could lead to busted pinion/ring gear tooths, pinion shaft, or the actual case could become chewed up and useless under extreme conditions.


By far the biggest failure with welded diffs in general, is that due from the stress you can crack the welds on it, when this has happened to some people it has locked the diff up. Just imagine that at 120mph, imagine it at 200mph and you will realize why no professional race teams use welded differentials. It also lacks highly in moderate to tight technical corners and autocrossing. Proper weld technique and placement is required for a good welded differential so defintely check into it if you are mind set on doing this mod. Some off-roaders swear by them, but those hardcore rigs do not get hardly any street mileage and when run hard the tires aren't gripping into asphalt and the tire gives away traction a lot easier...

The only Welded diff related problem I've actually heard of from 240SX owners is the welds breaking, probably because of shitty welds. People will cry and cry about breaking axles and pinions and wearing tires, but they are also the same people that don't run them. Most people that have them Acknowledge the driveablity problems and weld it in a way to be able to ignore the technical problems (read: they do it right)

There are the Driveablity problems, like push in the corners and the car will fight itself at low speeds. But I have seen plenty of track cars with Spools and Weldeds (Roadrace) and its something you have to adjust to.

It was for one Drift Day sooner or later yeah, Of coarse, thats an easier way to get a diff to seize than welding it. But the R200 will put up with a shit ton of abuse, some drifters in japan pack scrap metal into a VLSD for increased locking, the Casing and Output shafts deal with 400+ HP Clutch Kicks regular basis and wont put up a fight.
