jgkurz Posted November 1, 2003 Share Posted November 1, 2003 Now I know where this strange new vibration is coming from... At least I finally got into the 12's. Being the front u-joint, I'm glad it only bent instead of breaking. By the way, this was relatively new driveshaft with the best Nissan u-joints I could fit.

yo2001 Posted November 2, 2003 Share Posted November 2, 2003 That's pretty sick there. I would think you break the halfshafts before the driveshaft Quote Link to comment Share on other sites More sharing options...

Hybrid240z Posted November 2, 2003 Share Posted November 2, 2003 Are you sure you didn't hit that thing with a sledge hammer for sh!ts and grins? Just messing, but I think that puts a serious message for all us hybriders out there. Use a driveshaft loop and start checking the driveshaft/ujoints just in case.

Sparky Posted November 2, 2003 Share Posted November 2, 2003 wow. I dont think ive ever seen that before. I also would expect a Halfshaft to go before the driveshaft. *goes to summit catalog to order drive shaft loop. 8) Quote Link to comment Share on other sites More sharing options...
Guest Nic-Rebel450CA Posted November 2, 2003 Share Posted November 2, 2003 I havent seen something twisted like that since I made my Ex reeeally mad BTW, as a note to all of use, if you score or mark a dashed straight line on your axles, you can easily check them from time to time with a strait-edge to see if there is even the slightest twisting. From what I have been told, once the axle starts to twist it basically gets exponentially worse. Quote Link to comment Share on other sites More sharing options...
dot Posted November 2, 2003 Share Posted November 2, 2003 I haven’t seen a part twist like that. Usually the U-joint will fail first. I have to wonder if that part was properly heat treated. It should break before it twists. Cheers…:::Glenn Quote Link to comment Share on other sites More sharing options...
fl327 Posted November 3, 2003 Share Posted November 3, 2003 how much end play on driveshaft yoke??? im thinking not enough, and that could have caused that crunch. wow, thats a better photo than my old mustache bar! Quote Link to comment Share on other sites More sharing options...
jgkurz Posted November 3, 2003 Author Share Posted November 3, 2003 I had the driveshaft length made with 3/4 inch end play. When I pulled the transmission yesterday it had 1/16 inch end play due to the bent flange. I've been talking to several folks on this and I've come to the conclusion that the flange was made of poor quality not the u-joint. If anything should break first it should be the u-joint not the flange. The Nissan u-joint actually was the part that saved my car from serious damage. A lesser brand may have broke rather than just bending. Anyone have a source where I could buy a new quality yoke/flange that will fit my 83 Nissan T-5?

jgkurz Posted November 3, 2003 Author Share Posted November 3, 2003 Hi Mark, I've always thought that having an IRS was better as it related to the driveline. In a Z car the driveline is fixed unlike a live axle that moves up and down with the suspension. Quote Link to comment Share on other sites More sharing options...
260DET Posted November 3, 2003 Share Posted November 3, 2003 Someone I know used parts from a Nissan Navara 4x4 three inch diameter driveshaft. But the gearbox he had was ex a Nissan Sylvia which is basically a 280ZX box. Don't have any more info than that. Quote Link to comment Share on other sites More sharing options...
Scottie-GNZ Posted November 3, 2003 Share Posted November 3, 2003 More proof that drag racing and the IRS don't mix well! That's crap unless it was meant to be a joke. jgkurz, your mistake is running Nissan u-joints. Since you have a GM tranny, have a 3" diameter shaft made with the big Spicer u-joints and have them put the NEAPCO adaptor flange on the end of the shaft. That adapts the big Spicer joint to the R200 flange. I forgot the part# for the flange but the driveline shop will know it. Quote Link to comment Share on other sites More sharing options...
jgkurz Posted November 3, 2003 Author Share Posted November 3, 2003 Scottie, Thanks for the advice, but I think I'm stuck with what I already have. Supposedly the 83 Nissan T-5 I'm using has a 24 spline yoke that wasn't used on any other transmission. The GM and Ford version of the T-5 have different input and output splines I'm told. I'd love to go to a better part if only I could find a decent yoke that fit my transmission. My driveline shop said they looked all over for a new yoke that fit my T-5 so performance u-joints were not even an option. I looked at the receipt for my driveline and the flange that failed was made by PTI. I've never heard of these folks. Quote Link to comment Share on other sites More sharing options...
maichor Posted November 3, 2003 Share Posted November 3, 2003 Scottie, what about an adapter to go to an R230 from a GM shaft? That is what I am looking for. The driveshaft shop didn't seem to know about one. I could use the help. NEAPCO? I'll check into it. Quote Link to comment Share on other sites More sharing options...
Scottie-GNZ Posted November 3, 2003 Share Posted November 3, 2003 You say you are using a GM shaft but what u-joint are you using on the diff side? The NEAPCO adaptor I am referring to used the big u-joints on one side and bolted up to the R200 flange. I doubt that it was made specifically for the R200 and it is more likely that some other application uses a flange with the same bolt pattern as the R200. Rather than tell them R230 (HUH? WHAT?) you need to take an R230 flange in to them and have them find a u-joint flange that has the same bolt pattern. Quote Link to comment Share on other sites More sharing options...
maichor Posted November 4, 2003 Share Posted November 4, 2003 OK! Sounds good. I am using a Nitrous ready Denny's driveshaft with the large U-joints. It is definitely a heavier duty U-joint than the Stock LS1 Camaro driveshaft. I probably should pull the part# off of them when I get home.
