I have a 91 fastback with 275km on it. As of late it has been making a whining noise from the back end even when in neutral and rolling. Noise is louder when decelerating.
I took it to Nissan and they said the diff is going so just wondering what my options are here? I was told a new diff from Nissan would be about $1700 plus labour so that is not an option.
Is there a bearing and seal kit for this from Nissan? I don’t have the time to rebuild this but would really like to keep the car going. Can anybody recommend a good shop which has experience with 240sx VLSD repairs in West Toronto or Mississauga area.
ur best bet is to purchase a used vlsd off of someone here on son. Or im sure theres some people basically giving away their open diffs that u could throw on just to keep it going
other than that if ur going to spend 1700 at nissan(which u wouldnt)…put in a tomei or something
S13 VLSD isnt affected by hicas, only by ABS. So if your car is non ABS and you have an ABS diff you want to buy, than you need an ABS driveshaft. They are cheap usually 50 bucks ? on son. However, you can still use your driveshaft with whatever diff, it just wont line up as nicely and is harder to install, its 1/4 inch length difference, and it will wear you support bearing and output bearing faster.
BTW, I have an open diff for sale if you want. NON-Abs, you can take it to nissan and be like take the centre piece out of this and shove it in the other one and replace the bearings… or swap the whole thing
The last time I changed the diff oil which was about a month ago I noticed some fine metallic slivers about 0.5 cm long attached to the drain plug. I assume this is not normal and likely is some bearing starting to disintegrate.
What usually starts to go in these diffs the pinion gear, bearings, or both? The whine is most noticeable gearing down with power applied, but even if I put the MT in neutral the whine continues just not as loud.
Is it common for a VLSD to wear out like this? This car sees a lot of highway distance and has been driven hard, but respectfully. I don’t think I read on this forum of another LSD wearing out just lots of swapping the open for LSD going on.
