Right now I have a broken/in-the-process-of-breaking collar gear, and I'm not repairing it immediately. Mostly because I want a better part and am waiting for the community effort to put one together, but also because of the risk that the angle gear input shaft will be stripped and/or the collar gear will be fused to the transmission, and the repair will end up costing me thousands of dollars. <p>The problem with my hesitancy is that driving it around like this increases the chances of the angle gear input shaft being stripped when I finally do repair it. <p>So right now I'm driving around with the hand brake up two clicks to disable AWD. Logic being that torque will not be applied to the angle gear/collar gear and further destruction of the teeth will be avoided. Is this solid logic or just a dilusion that I am helping anything? Do I risk breaking anything else by riding around like this? Thanks in advance for any info or advice..

Re: Riding with AWD "disabled" (MeisterBrau)

If you're going that route, pull the fuse, not the e-brake...<p>That being said, no load is better than whatever the car would normally do - however those parts are always moving, even with the driveshaft removed, so you do still risk irreparable damage driving it around <IMG NAME="icon" SRC="http://********************/smile/emthdown.gif" BORDER="0">

Adam is right.<p>Torque will still be on the collar, just not on the angle gear. With the failed collar, I believe you will be driving around with front-left wheel traction only <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0">

It's broken or it's not broken, it can't be a little bit pregnant, it either is or it isn't!<br><B>BAD idea</B> to leave it alone as you will be waiting a very long time (forever) for an "upgraded" gear.

Re: (phuz)

You will never have one-wheel drive, unless a half shaft breaks, but even then you'll effectively by zero-wheel drive since the R has open diffs and I don't think TRACS is up to that task haha.

Alex, I sent my old SM an email asking him to inquire the tech about the fitment of the new collar on the shaft. He said they come preassembled with the new transmissions, but the protocol requires them to heat up the new collar in an oven (for expansion purposes) and then place it on the spline shaft and allow it to cool. After its on, it requires a puller to remove. He said there is VERY little play which leads me to believe the teeth are meshing quite nicely, which contradicts what you showed me on the VS page where the teeth are only in about 50% mesh. <br>Thoughts?

I wouldn't think a tight fit, perfect meshed unit would have failure issues, but if they are anything like what you are describing, then yes...big time.

Re: (FEO)

Yes, there was moderate wear only on the angle gear side. That's the side that was loose. But it slid on the transmission shaft easily too.<p>I'd love to see a how tightly a brand new angle gear and sleeve fit together.
