trackzpeed Posted November 10, 2017 Share Posted November 10, 2017 I have come to realize that DSS stands for Drive Shit Shop not Drive Shaft Shop. I purchased their full bolt on axle kit and stub axles rated to 800 hp. Absolutely none of their "bolt on" product bolts on my Z. The adapter to diff stub axle is designed wrong and the hardware they sent will never fit....... After 3 weeks of doing my own research and sourcing my own hardware I finally came up with a solution to make the adpter work and fit albeit with ZERO input or help from DSS. Tonight, I went to test fit the new OEM bearings on the new wheel stub axles from DSS and they slop all around! The bearing surface on their stub axles measures 30mm and my stock stubs are 32mm. I am so freakin pissed right now! My car is totally torn down and nothing DSS sent me fits or is compatible with my 240Z. DSS part numbers are DAR-1 and DAR-WHEEL......... DO NOT BUY THIS CRAP! The only thing bolt on about it is that it bolts to itself beautifully. To bad it just won't bolt into a Z as advertised and the tech support doesn't know jack squat about Datsuns or its own product to help. Now I get the joy of trying to get my money back..... Oh joy! Im warning the Z community to buyer beware. This has been a terrible experience. Jim 1 Quote Link to comment Share on other sites More sharing options...
trackzpeed Posted November 11, 2017 Author Share Posted November 11, 2017 Update..... Just to be fair. Lee at DSS is working to fix the problem. Apparently they sent me the wrong stub axles and will make the situation right ASAP. Updates to follow as the "fix" unfolds. Quote Link to comment Share on other sites More sharing options...

trackzpeed Posted November 12, 2017 Author Share Posted November 12, 2017 Thanks..... I'm going to give them a chance to make this right, if they can't, you are my first call. Quote Link to comment Share on other sites More sharing options...
AkumaY Posted November 13, 2017 Share Posted November 13, 2017 i have this same problem, i cant figure out how you are supposed to mount the 930 cv adapter onto the differential side stubs, there is no way to tighten the nuts. my project is on backburner so i havent spent much effort on trying to sort this out how did you end up doing it? pics would be great!

trackzpeed Posted November 13, 2017 Author Share Posted November 13, 2017 New hardware from Carr McMaster. I'm using hardened 3/8-16 bolts with lock material on the threads and thin grade 8 nuts on the back side of the flange. The hardware they supply will never work..... the stuff I sourced will hold up fine and the adapter is machined to hub centric around the diff stub axle so shear won't be a problem Make sure your bearing surface is 32mm and not 30 on your wheel stub axles. DSS is under the impression there are two sizes for the s30 and they sent me the smaller. I've been building Z's for 30 years and that's news to me..... but I'm giving them a chance to make it right.

AkumaY Posted November 15, 2017 Share Posted November 15, 2017 thanks for the info can you post up some pics? would be super helpful Quote Link to comment Share on other sites More sharing options...
trackzpeed Posted November 15, 2017 Author Share Posted November 15, 2017 Ill post some pics in my build log when I get them in....... Happy to help. Jim Quote Link to comment Share on other sites More sharing options...
trackzpeed Posted November 19, 2017 Author Share Posted November 19, 2017 New hardware. 3/8-24 3/4 inch with grade jam nuts and red lock tight torqued to 50lbs. Quote Link to comment Share on other sites More sharing options...
AkumaY Posted November 21, 2017 Share Posted November 21, 2017 PERFECT! thanks so much, ive been struggling with this one for a while, and when i called them, they acted like i was crazy. if they were designed right or smart, they wouldve counterbored the adapter bolt holes larger for nuts on the inside, completely opposite of what they have. if handy, would you happen to have those mcmaster part numbers? thanks again!

trackzpeed Posted November 21, 2017 Author Share Posted November 21, 2017 I did take time to grind off the top of the bolts flush with jam nut........... It also mushroomed the thread a bit which will create its own type of lock. Ill try to find the numbers but they were easy to find and source on their site. best of luck Jim Quote Link to comment Share on other sites More sharing options...

Probably a silly question, but can you just flip the bolts? So the nuts are on the other side? Quote Link to comment Share on other sites More sharing options...
trackzpeed Posted November 26, 2017 Author Share Posted November 26, 2017 No..... Not unless you machine the adapter and that's really hard with the stepped lip. Quote Link to comment Share on other sites More sharing options...
trackzpeed Posted December 16, 2017 Author Share Posted December 16, 2017 Well....... Lee at DSS is coming through for me. per his request, I'm sending the stub axles back along with my OEM 240Z stub axle. He wants to make this right, so they are going to custom machine stub axles for me based off of the specs of my OEM's. As frustrating as this has been, I have to give Lee props for trying to make it right in the end. Ill post up how this all turns out.

trackzpeed Posted January 11, 2018 Author Share Posted January 11, 2018 Well I finally got my parts back today..... I will know this weekend if they actually fit this time. Drive shaft shop said they would pre-assemble everything to minimize my time getting my car back together...... but they didn’t! They only managed to press in the wheel studs half ass crooked so I have something more to fix aside from pressing on the bearings for a third time. Buyer beware- drive shaft shop is one of the worst experiences I’ve had in a very long time. Jim Quote Link to comment Share on other sites More sharing options...
G-Tech Posted January 12, 2018 Share Posted January 12, 2018 It's amazing what a horrible experience your having with them. They have been around for so long you wouldnt think they would be that unprofessional. ...very good luck with this fitment, they better last a lifetime Quote Link to comment Share on other sites More sharing options...
trackzpeed Posted January 12, 2018 Author Share Posted January 12, 2018 Yep, sadly even Lee who I thought was in my corner screwed me too. I hope and pray these work or I’m going to start from scratch. Quote Link to comment Share on other sites More sharing options...
trackzpeed Posted January 14, 2018 Author Share Posted January 14, 2018 The axles are machined wrong again and continue to bind in the upright housing. I’m done and asking for a full refund. DSS has no idea what they are doing with Datsuns. Absolutely do not buy the this product. Starting over again. What a bummer. Jim Quote Link to comment Share on other sites More sharing options...
NewZed Posted January 14, 2018 Share Posted January 14, 2018 Curious what you mean by the axles are binding in the housing. Only the bearings should actually touch the housing. Maybe I missed where you determined exactly where the binding was. Might help DSS get it right. Quote Link to comment Share on other sites More sharing options...

He wants to make this right, so they are going to custom machine stub axles for me based off of the specs of my OEM's. It seems that what you're saying is that DSS could not copy the dimensions of a stock axle correctly. Not really clear what the problem is on the fit though, since the axle just has to fit inside the bearings and have a proper seat on the flange side. Binding would most likely be between the bearing inner race and the shaft. Not a huge deal, you could have sent them bearings also, so they could check fit. Seems like there might be poor communication. On November 19 you had something that was about ready to go back together. Then Lee offered to make it better, apparently by making a brand new part, that they do not currently offer. Somehow, something came back wrong, but you haven't really described what. Is it possible that DSS is not 100% responsible for these problems? It's their first time making a full 240Z axle, if I read your posts right. Looks like they're in that classic old situation of getting hammered for being too helpful. Quote Link to comment Share on other sites More sharing options...
