    280z Rear Suspension Uneven

    I've found spacers on Zcardepot that will let me use 240/260z insulators, so I've order new insulators for the front and rear. Here's an odd question for you all, would the fact that the fuel tank is primarily situated on the passenger side contribute to the height difference? I've got around half a tank of fuel, and the passenger side is a little less than 1/2" lower than the driver side (rear only). The front wheel gaps are even.

    So looking at the strut tower insulators, it looks like the driver's side insulator is torn and the centerpiece of the insulator has dropped out. I'm guessing that this is what is causing the driver's side to sit higher? Now here's the difficult question, I can't find 280z size rear insulators anywhere. I know you can use the 240/260 mounts, but this would lower the car and I've already got lowering springs on the vehicle. What are my options?

    I've found that Gabriel produces non-gas struts for our cars, do you think they would work fine with lowering springs?

    I'm thinking that maybe it's the KYBs. I just went outside and brought the rear of the car up far enough to lift the tires off of the ground. I let the car back down, and the passenger side went back to a 2 1/4" distance tire to fender. It would seem that maybe the strut isn't holding up? It would make sense, given that these struts apparently aren't good to use for lowering. Also, thank you for your help tonight, datzenmike! I appreciate it greatly.

    Both rear springs are marked "Tokico 5022R", are you saying that they may have worn at different rates? I've had the set on for ~4 years. What else is odd, is that before I took the car out today the passenger side was around 2 1/8" from tire to fender, it's dropped over the course of a short night's worth of driving.

    280z Rear Suspension Uneven

    Good evening all, The rear suspension in my '75 280z is uneven, the driver's side is 2 1/4" from tire to fender lip, and the passenger side is 1 3/4" from tire to fender lip. I've adjusted the transverse link bushings (inner and outer) according to the manual by having people sit in the car as the bushing bolts are torqued to spec. I've got Tokico 5022 lowering springs in the rear, and KYB Gas struts. When I purchased this setup it was not known that KYB Gas struts aren't supposed to be used with lowering springs, and now I'm guessing that this is my issue. Would this be the most-likely culprit? Thanks in advance to anyone who can point me in the right direction. Also, what struts and vendors should I use? MSA seems to be sold out of Tokico HPs.

    On a different note, does the wear pattern on the ring look good?

    Given that I purchased this late last year eBay may not be able to assist with some sort of refund/return. I should've done a better job of checking the diff to verify that it was an LSD! The best I can do now is leave some professionally-worded negative comments on Yelp/Google for his business and hope to steer others away from Cali-Datsun.

    Lesson learned. I used to think that ~98% was ok for ebay scores. I suppose the only good thing is that the diff, although open, is functional. Time to reseal and move on with other projects.

    I asked who the vendor was, "That's none of your business, why did it take you so long to figure out it wasn't a lsd?". Classic deflect and also convenient the vendor is gone. I'm getting ebay involved

    His response Thank you for the information. We have a 30 day warranty or exchange policy. Since its been several months there is no longer any remaining warranty. We are resellers of these parts and there is no way for us to test a differential. The supplier we purchased this from is out of the county for a few weeks. I will see what he says, however since its been so long there is no way to verify this information, but I will try. Sorry about that.

    Well, it looks like California Datsun sold an open diff and passed it for a CLSD. Time to contact them and see about a refund.

    Thanks for the link! If it were open the wheels should spin in opposite directions when the driveshaft is spun, right? Because this unit turns the wheels in the same direction when turning the driveshaft. Strange thing is that if I turn a half-shaft in one direction, the other half-shaft turns in the opposite direction.

    So maybe this is a VLSD unit? Would that explain the lack of coupling strength at low speeds (like hand-turning the driveshaft)?

    37:10 AL 6 11 24 There's no crosspin in the spider gears so I'm certain this is an lsd. I haven't pulled the carrier out yet to check it
