LSD for Front diff in GTR trans

[almighty4wd]

Here's something that Jay got me thinking when he mentioned his Frankenprotege has a front lsd. Would/could the Quaife for the G trans work? I've a 2way for the rear, the viscous center, now I just need something for the front. any idears?

final drive ratio is different

[almighty4wd]

well crappy hoes. anyone know of a front lsd with the correct ratio?

[therieldeal]

actually wait, the quaife gets bolted to your stock ring gear, so it might work. count the splines on your GTR intermediate shaft

GTR and GTX front diffs that go in the trans are the SAME! I have had both transmissions apart next to each other- mirror image, with minor differences.

Craig, you don't need a diff in the front with the one in the rear, and the GTR in the trans... your all good. Unless the center viscous is bad...

[therieldeal]

i know the gtx/gtr diffs are about the same, i think he was asking if the FWD g-series diffs were the same.

I got the impression that he was asking about the awd? since he has an awd. for that matter the 2wd lsd from quaife will not work in the AWD version two totally different difs alltogether..

hmmmm, yeah I'm just being greedy with traction. I don't need one, but I think it would be amusing to have all 4 tearing the gravel.

[jay]

All 4 will tear the gravel. Pix of the rallycar show this to be the case...along with my old GTX with the stock BPT box, throwing dirt from all 4. That centerdiff sends most of the torque to the back where it belongs anyhow. Any open-diff issues up front come out in the wash, with enough underhood grunt.
The jury is still out as to whether the front diff on the rallycar is LS or open. What I think is, the guy who sold it to me was thinking about the centerdiff, which is indeed LS on that trans. When I pressed him on it, he said again that no, the front diff is LS as well but I ain't about to split the case to find out. Right now, the rallycar is on jackstnds with no suspension on the driver side; those shocks ar at Dave Clark Motorsports, to be used as templates for the new stuff. Once I can run it without having loose rotating bits flaying about wherever they feel like, I'll jack the other side up, put it in gear, fire it up and see what happens when I stop one front wheel. That oughtta settle it, yes?

[almighty4wd]

sounds good to me

[jay]

OK, I made sure I could, and got all 4 corners off the ground and fired it up. The rear diff is lsd so is the centerdiff, but the front diff is open as I suspected. But it still throws dirt from all 4...

[almighty4wd]

sweet deal. Good to know I'll have at least 3 pushing power on the ice or when I go 4-wheeling and get one off the ground

[jay]

Yah it makes me wonder though, Dave Hintz who is very quick in his Sooby, had a front diff let go on one rally, and he talked about "struggling with the car" with a replacement open front diff... gee I wonder what a LSD front diff would be like? Am I "struggling" now and don't know what I'm missing? Survey sez duh, yeah.
