 |
|
late last night my brother and I were rallying out on our parrents property. whe have this great little corse for motor bikes that has been sitting for a while and the grass has started to grow up there again. We decided to take the baja down on the lower overgrown trails. It was great at first it seemed to go down there quite easy. we were toolin' around on the burms and the little woop section but when we tried to come up from the bottom of the grassy dirt hill. We were stuck! He tried for a matter of 15minutes or so as I watched. What I noticed was the wheele which seemed to have the best grip on the ground wouldn't turn while the while that was slipping on the grass was winding away. It would seem ideal to be able to lock the wheeles togather for a situation like that. We have a stock 68' bug tranny in there and have been thinking of upgrading to a bus tranny. Is there any added traction capabilities of the bus tranny or am I just pipe dreaming of a solution to the wheel sliping situation?
Just so you know our tires have a light tread pattern on them and we need to buy some nice off road tires I'm sure that will help.

| If you up grade to the bus box, make sure you get the super diff in it, works like limited slip. I had that happen years ago and my buddy said his dad pulled the e- brake just enough to put presure on the spinning side to tranfer power to the not spinning side. Didn't make sense but it saved me a tow truck bill. |

An aftermarket super diff is just an open diff, exactly like stock, just 2 more spider gears. It will function exactly the same. One wheel will still spin freely when its traction is less. |

I was reading in the baja and dunebuggie book that it is not worth it to have a limited slip differential and instead what they recommended is to have stearing breaks which are controllable Ebrakes basicly one lever for each wheel. so if i was stuck like the other night and I look out the window behind me to see that the wheel that is spinning is not getting traction i would pull the stearing break for the other side giving it a little resistance transfering the power from the free spinning wheel to the one that I think should turn. I was excited to hear this consept and it makes perfect sense. Now my question is what do you do for stearing breaks? Is there aftermarket part that anybody has tried and likes? or do you think Im better off fabricating my own?

| But with an LSD you don't get stuck in the first place. |

yeah i never understood that, why is it just an "open" diff? it would make more sense to come from the factory with locked diff or limited slip, wouldnt it?
but i have heard steering/cutting brakes work well, and i know chirco has a few kits, and a few others such as cip1.com may have them, heres chirco http://www.chirco.com/cgi-bin/chirco.storefront/3ff8b33904a21628274040772015064c/Search/Run just type in "cutting brake" and theres like 15 entries

It would, but an 091 Bus LSD has 22 precisely machined parts in it, a factory open diff has 7. This means an LSD costs more to manufacture. And besides, VWoA thinks an LSD is too much for Americans to handle. That's why VWoA has never offered an LSD on any car sold here. |

| bugpack sells a turning brake kit or steering brakes as chrispoage called them. it is basically two parking brake handles without the rachet lock that a stock parking brake handle has. i believe it bolts up in the stock location. i have a stock trans axle and when and if it breaks i'll replace it with a transform transaxle with a superdiff, heavy duty sidecovers and a different ring gear. i run 27 inch tall bfg's and the gearing is kinda goofy in 4th. i've been stuck b-4 and i think the turning brakes would have gotten me out. now i carry a small shovel and tow straps. |
