I'm leaning torwards the TTR U Joint half shafts as the rumor has it that the new CV axles are failing due to the quality of the new CVs.
This news to me. All of the conversions I have seen here in the US utilize the tried and true Lobro (VW) joints, never heard of a problem.
Hey Mike;
This is what I have been reading about on this forum and others. Sue Miller stopped selling the CV jointed shafts because of the massive failures and TTR says the geometry doesn't work and cannot find a solution. From what I have read, there are two issues, one is the range of motion and the shortness of the shaft on the Elans which over extends the CV joints to failure. Apparently, if you jack the car up and rotate the wheels, the CV's would lock up or clunk badly. Secondly, when these CV shafts first came out, the Lobro CV's were being made better and no failures of note occured. But with the new batch or design, they had been failing left and right. Well, that is what I got from reading numerious posts.
I like the TTR system, 2 U joints on both ends, but you have to upgrade to the steel diff output shafts as the system is so direct, it will undoubtedly twist the cast parts apart. Unfortunately, I keep on looking at the aluminum ears on my diff, very fragile and time has not been kind. So I can see a possible failure using this system. But the idea that when a U joint fails, it's a 20 dollar repair appeals to me. On my other Elan, I have a cross of rubber rotoflexes on the inboard side and U joints on the outboard. At least this system will cushion the torque on the diff and I only have to worry about the two inboard donuts. But I cannot find find who still makes them. It may have been Spyder in the early days, but not sure. BTW what are you using on the 26R conversion? Allan
