tamo3 Posted April 30, 2012 Share Posted April 30, 2012 Hi, I'm having hard time to figure out how to remove CV from R200 diff. When I remove Diff from z31, right side of CV popped out easily. However, left side of diff is hard. I don't want to damage CV, so I've been careful about not to messing up. Since CV is connected, I can't use puller. Does anyone know easy way to remove CV from Diff? Thanks, tamo3 Quote Link to comment Share on other sites More sharing options...
rossman Posted April 30, 2012 Share Posted April 30, 2012 Use a flat prybar in between the pumpkin and the CV flange. It will pop out, just needs a little convincing. Quote Link to comment Share on other sites More sharing options...
tamo3 Posted April 30, 2012 Author Share Posted April 30, 2012 Thanks Rossman, I was using flat prybar in between the pumpkin and the CV flange and banging hammer. I was afraid of damaging CV flange. I will try harder. By the way, your project is awesome! Thanks, tamo3 Quote Link to comment Share on other sites More sharing options...
Leon Posted April 30, 2012 Share Posted April 30, 2012 I use two screwdrivers on either side of the flange, so that I'm not binding the shaft. Pops right out. Quote Link to comment Share on other sites More sharing options...
tamo3 Posted April 30, 2012 Author Share Posted April 30, 2012 Thanks Leon for your tips. I will try your method too. Thanks, tamo3 Quote Link to comment Share on other sites More sharing options...
RebekahsZ Posted April 30, 2012 Share Posted April 30, 2012 (edited) I use either a wood splitting wedge or a cold chisel (or is it coal chisel?) (which is basically a small wedge). I insert the wedge between the axle and the differential case and tap it in until the axle releases. A lot easier for me than prying-I can't find a place to fulcrum the pry bar or screwdriver.

RebekahsZ Posted May 3, 2012 Share Posted May 3, 2012 How did it go? What finally worked? Quote Link to comment Share on other sites More sharing options...
tamo3 Posted May 4, 2012 Author Share Posted May 4, 2012 Hi RebekahsZ, I did not have time to working on diff this week. Since i have only one screw long enough driver and want to get wedge or a cold chisel that you suggested. That's sound easier. I worked Xenon Airdam installation at lunch break. Oh, and I got 3.9 final gear too. Will try work on diff over the weekend. Thanks, tamo3 Quote Link to comment Share on other sites More sharing options...
Leon Posted May 4, 2012 Share Posted May 4, 2012 That ring gear is pretty much useless without its matching pinion. Quote Link to comment Share on other sites More sharing options...
tamo3 Posted May 4, 2012 Author Share Posted May 4, 2012 Hi Leon, I got R200 3.7 CLSD(37:10). My understanding is both are same pinion used 10 tooth and I thought the final gears are interchangeable. Quote Link to comment Share on other sites More sharing options...
JMortensen Posted May 4, 2012 Share Posted May 4, 2012 No, definitely not the same 10 tooth pinion. The pitch of the gear will be different because the ring gear has fewer teeth. You really don't want to swap gears even from one 3.90 to another 3.90 if you can avoid it. The ring and pinion can be swapped from one housing to the other, but you need the ring AND the pinion. Much easier to swap the LSD to the 3.90 housing if you still have it. Quote Link to comment Share on other sites More sharing options...
tamo3 Posted May 4, 2012 Author Share Posted May 4, 2012 JMortensen, Thanks for your advice. I did not know that. Quote Link to comment Share on other sites More sharing options...
RebekahsZ Posted May 5, 2012 Share Posted May 5, 2012 (edited) I just saw a 3.70 CLSD se on eBay for $300. Of course that was the morning after. Damn sleep! Why do we need it? I took some photos of the chisel technique. Put the chisel between the axle and the case. Strike the chisel with a straight blow to get it started out, then strike the chisel with a glancing blow to pop it all the way out. Try to catch it so you don't goof up the splines when it hits the concrete. Pictures posted out of order.

tamo3 Posted May 7, 2012 Author Share Posted May 7, 2012 Congrats for gettign 3.70 CLSD for good price! I tried using two screwdrivers to pull out CV Axis, but it did not work. Then I used flat prybar with angle side. Using the principle of the lever, CV Axis came off without banging hammer much. How easy it was... Wrapped CV axis and put it into storage for now. I got rest of 3.9 R200 as JMortensen recommended. Man, I paid $50 for the fial ring and $90 for the leftover staff. Since I clean up final gear ring, the marker is gone, Pick 'N Pull won't let me get refund... I should've got entire pumpkin at the first place.

RebekahsZ Posted May 8, 2012 Share Posted May 8, 2012 (edited) No-I blew it and didn't get the diff! I fell asleep and failed to get a last minute bid in....(sad face). Agree, always get the whole diff. Edited May 8, 2012 by RebekahsZ Quote Link to comment Share on other sites More sharing options...
