If you're going to SAS later, it really wouldn't be worth the money to get stronger cv's. They'd be custom I'm pretty sure, and custom usually means $
They're saying stronger cv's aren't needed, and I'd agree. I wheeled mine for a couple months with torn boots, almost totally dry joints, and they were clicking while turning either way. I still kept one for a spare, though I don't plan to need it.

Fix the steering weaknesses, and you're pretty much set!

You can get Porsche joints. They are spendy. On a CV, the joints are the weak part, the shafts seldom break. TC managed it, but I have a feeling that was old crap stuck in there from a previous issue.

Carry spares, do the stud mod, and practice changing them once in the driveway. Troy and I together can do one pretty damn quick. Unless troy's skid plate gets cranky. Then I spend a few minutes cussing. But still. Pretty quick.

Sorry but what is a stud mod??????????????

Basically, the stud mod is to knock out the pressed in studs and replace them with bolts. Being able to get the bolts out of the way makes it MUCH easier to get the CV out.

I broke a shaft with the front (only) locked, in compound low, on the throttle, on rock. In other words, I was sending approx 36,000 ft-lbs of torque to the one axle. Not exactly unsurprising that it broke...

I tried to show someone that page a month ago & it wasn't up. I'm wondering if they know or care that it's blank.

The other way is to pound out the studs & grind off the locking ridges, then you don't have to buy new hardware.

Is there a standard size bolt to use when doing this? I searched all over YT and TTORA and can't find the bolt size. I'd like to do this, but I'd like to have the hardware ahead of time...

(Now, if one of you guys goes and finds a thread with that info in it, I'm gonna flip...)

CJ, I don't know how this works on Third gens. Unless, you have a first or second gen we don't know about

Yeah, I wish... If I did, it would look like yours...



Oh well, looks like I'll have to guinea pig it. When I do it, I'll make sure to post up for posterity's sake.

Third gens use the clamshell diff where the CV is splined and goes straight into the diff - there are no bolts.

The bolt size is M12-1.25x30mm - same as used on the brake calipers, crossmembers, diff/body mount, and a few other places - buy plenty to have as spares.

I don't know, but it doesn't matter, they're not interchangeable.

The clamshell diff is high pinion, so the R&P should be ~30% stronger.
