Arnold Posted July 13, 2016 Share Posted July 13, 2016 Hi all My mechanic has just had my gearbox reconditioned by a company who fitted a Quaife LSD differential at the same time. Now he's trying to refit the box to my Glanza and he's saying the drive shafts wont fit back into either side of the gearbox. He thinks I've ordered the wrong diff. The gearbox recon people have fitted it OK, and Quaife said it's the correct part, and being a direct fit, have never had this issue reported to them. My mechanic says the shafts are too big to go in though. Any ideas what the issue might be? Has anyone else experienced this? Cheers!Arnold Quote Link to post Share on other sites

Phil Posted July 13, 2016 Share Posted July 13, 2016 Have a quaife here that I ran before and no fitment issues with driveshaftsNot helpful I know but that my experience lolPhil Quote Link to post Share on other sites
Socks Posted July 13, 2016 Share Posted July 13, 2016 I have seen differences in the inner cup sizes and shaft thickness. But certainly NOT in the spline/size of the inner CV shaft. Where did you buy the diff from? Quote Link to post Share on other sites
jayc-glanza17 Posted July 13, 2016 Share Posted July 13, 2016 Get some pics..However the spline has never been issue before like socks said.Only thing might be the circlip on end of shaft.. Quote Link to post Share on other sites
maddox710 Posted July 13, 2016 Share Posted July 13, 2016 Sounds like a numpty Quote Link to post Share on other sites
Phil Posted July 13, 2016 Share Posted July 13, 2016 Have had a different quaife diff a year or two back that had serious circlip issues !Took a sledge hammer to remove lolPhil Quote Link to post Share on other sites
Arnold Posted July 14, 2016 Author Share Posted July 14, 2016 (edited) Hey all Well he pushed the shaft into the box OK but it's like the teeth on the shaft don't want to go into the diff. Quaife said it can be a stiff fit, so he ended up using a lot of force to get it in, and even so, he's saying it's still not all the way there. He said he's never seen it this tough to put in before (he does gearbox changes all the time). As it stands, the shaft looks like it should still go in a few more MM each side, but it won't go any further. The Quaife was brand new from Quaife directly, and they confirmed it was the right part! I'll get some photos up shortly. Edited July 14, 2016 by Arnold Quote Link to post Share on other sites
Arnold Posted July 14, 2016 Author Share Posted July 14, 2016 Here's how far we can get them in. Not sure if that's safe enough to drive like that? My mechanic says they're definitely not coming out. Quote Link to post Share on other sites
daniel_g Posted July 14, 2016 Share Posted July 14, 2016 There has been threads in the past where people have sold boxes cheap because they have a quaif that wont come out. Quote Link to post Share on other sites
5e colin Posted July 14, 2016 Share Posted July 14, 2016 (edited) deffo looks like it needs another7 or 8mm to go if there not going deeper theu must be hitting something i think use tripod gear puller and a u shaped bracket to go over cup and drill a hole in the u bar that way you can pull them out without damaging cup Edited July 14, 2016 by 5e colin Quote Link to post Share on other sites
Phil Posted July 14, 2016 Share Posted July 14, 2016 Best way to work that in is drive her, like the mechanic says they can't come out really once the other end is in place Phil Quote Link to post Share on other sites
fiddlersport Posted July 15, 2016 Share Posted July 15, 2016 ring on the cup which locks the cup into position ?stop ring its called Quote Link to post Share on other sites
5e colin Posted July 15, 2016 Share Posted July 15, 2016 Best way to work that in is drive her, like the mechanic says they can't come out really once the other end is in placePhil tut tut on that if the shaft aint seated propperly then the splines open the gearbox seal leavin oil seap out amigo !!!

ROTABOOST Posted July 15, 2016 Share Posted July 15, 2016 My quaife was an absolute nightmare getting the shaft cups out of the diff. It's more than likely just a really stiff fitment, as Phil said above I also had to beat the death out of my shaft to remove it from the box, to the point where I was certain I was going to damage the aluminium gearbox case. Best way to tell if it's the clip is pull the shaft out and remove the clip, if the shaft slides all the way in then you know it's the clip causing your problem Quote Link to post Share on other sites
Phil Posted July 16, 2016 Share Posted July 16, 2016 tut tut on that if the shaft aint seated propperly then the splines open the gearbox seal leavin oil seap out amigo !!!Sorry im imagining a quick little jaunt down a bumpy road followed by checked to see if they have worked themselves abit looser then s tap inward from the owner.Not advocating just hoping for the best, sorry if it came across that way. Just know how frustrating the inner circlip can be on these Phil Quote Link to post Share on other sites
Arnold Posted July 18, 2016 Author Share Posted July 18, 2016 (edited) When the inner clip wasn't on, he said it still had the same stiffness / resistance preventing it from going in, so he didn't think it was a clip issue. I just want to know really if it's safe / ok to leave it as shown in the images, or should he continue bashing away to get it on further?

Starlet__SR Posted July 18, 2016 Share Posted July 18, 2016 Id be tempted to pull it all apart. Remove the diff and try fitting the driveshaft cups on a bench. See where the issue lies, could be a machining fault. I had one on my ZR a few years back where the angle between the splines was a couple of degrees out. Sent it back and had it checked. New one was the correct angle. No issues after. Quote Link to post Share on other sites
TimD Posted July 18, 2016 Share Posted July 18, 2016 As above, you know something isn't right, the only way to find out what is to remove it all and inspect. A pain in the ass, but it's part of the game we play. Quote Link to post Share on other sites

alkapone Posted December 10, 2016 Share Posted December 10, 2016 Was this ever sorted. I just fitted a quaife and have the exact same issue. Quote Link to post Share on other sites
Arnold Posted December 20, 2016 Author Share Posted December 20, 2016 (edited) Yeah to update the thread, I took it back to Quaife. They modified the side gears within the diff so now the shafts slide in and out with no problems at all. What a difference it makes having this thing fitted!
