  1. I just rebuilt my Diff. Z car depot and Z carsource both sell Nissan Bearings. I too wanted Nissan Bearings. I don't think Whitehead is delayed because of adding to the order. I think they are just overwhelmed with orders. He was supposed to get back to me about a price on a built diff and never did. And my stubaxles i ordered 5yrs ago was something he said would be done in 6 weeks and i waited 9months. I only dealt with waiting that long because it was winter and im in NY. I was breaking stock axles and they were the only ones at the time offering stronger ones.
  2. This sucks to hear because they offer good parts and services but nothing has changed atleast in the 5yrs since my purchase of stub axles. I had a huge delay on stub axles i ordered from them . 9 months i waited for them when they said 6 weeks when i ordered. Ofcoarse they blamed it on their supplier then also. Good luck getting money back from them. Most places like that won't give you anything back, and they are in Canada so i dont know how that works if they dont give money back upon requesting it.
  3. Thank You, That is alot of gear! I was happy with my 3.54's. There is 1 r200 i see on ebay w/ 3.54's for $600 but you never know the actual condition, i cant even see what is wrong with the gears i have but i changed bearings, backlash, preload, pinion depth and couldnt get the noise to go away. Put my other diff in and noise gone.. I have someone locally willing to sell me his w/ 3.70 for a little cheaper. I am going to pick that one up. I just last night rebuilt my other diff with 3.90 gears and i can tell the difference for sure.
  4. Not a bad thought. I have a LS with 500hp and a 6-speed so i do want as much gear as possible.
  5. So funny, the different worlds s30 owners and s130 owners live.
  6. Good to know, Thank you. My280zx normally came with 3.93's, it had to be the turbo model to get 3.54. I thought the s30 would've been 3.93 also. Basically like i said, i only need the gears but if i have to buy the whole rear end i will.
  7. Title should say it all. I don't need the whole rear end unless that is the only way you would sell them. I hurt the gears in mine. Hoping someone has something they are willing to part with. Thank you
  8. Here is a pic of my t-56. The shifter is in the rear most position on the tranny. it fell right in place of where the stock shifter used to be. mine came with an adapter to move the shifter over closed to driver side but it really didnt need it
  9. When the problem 1st happened i checked the drain plug and there was metal shavings on the magnetic end. After having rebuilt and the noise came back, i once again found shavings. I drove for a week since i kinda new it was just the bearing, there was no more shavings and the noise stayed consistent.
  10. When he rebuilt it he showed me one of the bearing races he took out and it had a chatter mark on it. We both agreed that was most likely the cause of the excessive whinning that i heard which made me have it rebuilt in the 1st place. im assuming at this point that it happened again (the chatter marks on the race). i will certainly inspect it when i take it apart.
  11. I am going to have to rebuild the diff myself and i have seen a couple you tube videos and i have a factory manual but i also wanted to see if anyone here has any good write-ups. i just want to get as much info as possible to fill in blanks were mayb a you tube video skipped over something or at certain steps my manual gets confusing. The search feature on this site didnt give me any great results. i am mechanical enough to do it, i have all the tools. just sometimes i say its best to pay the professionals and this time it back fired on me. i know there are r200's for the s13's also i believe and so i put my model specifically in the title incase there are differences. The story behind this: i have a 83 280zx with a LS swap and so i had Quaife internals installed 10yrs ago. Last year i had a pinion bearing go bad. i couldnt get ahold of the guy who originally did it so i had someone else "reputable" do it and they didnt put enough preload in it. he straight up told be he put about 4inlbs of preload in. ofcoarse the pinion bearing started whinning pretty good again. i even put it on the lift, had one buddy bring the car up to 40mph while i listened underneath the car with a stethoscope to confirm the noise is indeed coming from the pinion bearing location. The guy who rebuilt it said it couldnt have been something he did and he would look at it when he had a chance but he was "real busy". I real A-hole basically
  12. I had mine rebuilt also with the quaife internals years ago. The crush sleeve got reused because I don't know of anywhere to get one. I know it sounds like a one time use but I don't think that's the case. The guy that rebuilt it was not concerned. It got reused and it's fine. I did need different shims because of the quaife unit needed different size shims so u will want to try to source something for that. I had a cnc mill at my disposal so I ended up making my own. I was gonna use synthetic oil but quaife said just use what is supposed to be in it, so I stayed away from synthetic...another company that might have some input would be zcarsource. You are gonna love that differential after this.
  13. I have a very similar setup (ls and t56). I kept the r200 and put quaife internals in and it has taken all kinds of abuse. It's been 10yrs and I just had a pinion bearing go in the diff. It cost about $500 to have the diff rebuilt with new bearings but that's not too bad. I bought custom stub axles from whitehead performance because I was snapping stub axles. They were pricey and I waited 6months for them but I don't worry about them anymore. And lastly, when I had them made I also had them made to fit 300zxt CV-JOINTS. That is a good upgrade for half shafts...that's my mods and it has been pretty solid. I drag race a few times a year and abuse it on the street too.
  14. i just looked up that kit. looks like a good deal to me. sounds like your happy keeping in pretty stock and just upgrading a little. certainly can only help the value and not hurt it.
  15. i just looked and i didnt see any "kit" let me know part # if you have one. i seen that the calipers they have are out of stock. Zcardepot and zcarsource are both good companies for replacement parts. there is getting to be more aftermarket parts for 280zx's also. not sure if you are into stock replacement/ mild upgrades / or performance parts? there is options for any way you want to go.
