I don't think installing the Peloquin is a DIY unless you are comfortable setting the ring and pinion backlash.

Trying to move forward from stopped on a slightly angled roadway only made the rear end fall off to the side with some forward motion.

IMHO good snow tires and a open diff is safe and very capable.

Mud & gravel & offroading a different animal though.

We just discovered this go sideways Peloquin tendency on sloping slippery roadbed from a stop. Had already made it up the icy hill that was forcing others to chain up, etc, only to get stuck parking on a slightly sideways sloped icy driveway. Chained one wheel and all was well. Overall, though, it performed very well.

hey teej, what kind of tires do you have on?

I've had the same experience in my driveway, but have Good Year Assurances on, not exactly a winter tire.

Although, they are rated for snow, but haven't been cutting it this winter...

We are running Nokian Hakkapellita studded, so I was surprised that they did not bite in. Ran the same tires last season (before the Peloquin) and did not experience the sideslip. But the driveway was 5 or 6" of powder over a packed/icy base at only slightly below freezing, so the treads loaded up and the studs were not grabbing. Chaining only one wheel was more a lazy experiment than anything but the difference was night and day.

Yep, that is a good winter tire right there. Need to go to the tire store!

I just ordered a rebuilt trans from AA Transaxle. I'm going with the stock gearing as it works well where I live. I discussed installing a Limited Slip (Peloquin) with Daryl and realized that with that set up you would need a locker to get true posi traction to both wheels. He mentioned these ZF LSD's made by VW that give you a fulltime 60/40 traction split to the rear wheels, this sounds like what I'm looking for. Traction on snow/ice from a stopped position with both wheels. My Van obviously is a two wheel drive. Hopefully this will improve my vans performance in winter conditions. I know the rebuilt trans will be a big improvement since mine is the original never rebuilt. I recently installed a 2.5 Suby which is awesome. I'll rebuild the Axles with the kit from Van-Cafe during the trans swap. :)

I did a search for "ZF" and got nothing. Could someone clue me in.

Thanks

I read somewhere that new OE 091 ZF LSDs are available. Perhaps a limited quantity made? The Peloquin TBD .. especially his Syncro (fully-lockable) version .. is a great option.

LSDs are a bit different than TBDs. Although not VW, you can see the difference here:

If you haven't you should go back through the thread and look at some of the videos. The peloquin provides traction to both wheels in most real world situations. Rear wheel traction for on road conditions could not get much better. Offroad rear wheel traction is rarely the shortcoming, usually it is gearing ang ground clearance.

Unfortunately this does not afaik exist. the nature of lsd and tbd requires some difference in wheel speed to engage the locking function. That is what a locking differential accomplishes. On the whole im very pleased with the peloquin/auto combination. It has greatly increased the traction and made driving in the snow fun, as i enjoy oversteer. The only drawback is the tendency to slide down slope when traversing a slope on slippery surfaces.

I started off at the base of a decent hill by my house (factoria Eastgate PR) and it was sheet ice/snow up that hill.. I took it with my Multivan/ which has the automatic, and a LSD from GW..

It's awesome. The policeman who was stuck said HELL NO.. buit I said hey, I live on the top of the hill and I think I can make it..

and I did.. the Nokian WR C tires and LSD.. AWESOME............ all I gotta say. That's the biz!

replace LSD with TBD or Peloquin in text above...no LSD for Vanagon automatic transmissions.

I bought whatever Gowesty has for the Automatic.

they call it a positrac.

yup, got the same in my tranny, that is the Peloquin Torque Biasing Differential (TBD)

Anyone know why Go Westy doesn't call it what it is - A Peloquin Torque Biasing Differential? Especially since Posi or Posi-traction is the trade marked (?) GM name for their LSD.

Same reason I call mine a Posi. Regular folks (some of them) understand 'Posi', none of them understand 'TBD'... To Be Determined?

Exactly, plus they do call it an ATB (Automatic Torque Biasing) Differential in the description.

Right - WTF is an 'ATB'? "Did you say 'ATV'?" :(

Tue Feb 05, 2013 11:48 pm

WTF is WTF?

This is getting ridiculous. There is a difference between an LSD and a TBD. That was my original point before things got weird.

LOL! Yes, you're right, but most people don't know that and aren't interested in the arcane details of a differential. Hell, most people have no idea how a diff works nor any other part of their car! ;) IMHO
