Never had an issue in snow or ice with mine, in fact I have never encountered any conditions in which the ATBs have had the slightest negative effect.

blackwolf, thank you for sharing your experience.
 There was a post in the old thread about car spin with the clutch depressed and a combination left side less traction,right side more traction. I wonder if someone experienced similar behaviour...or made this on purpose just for test.
Cheers, Delyan |

Might be worth sending a PM to TATRA805 on here it was his post that covered his experiences, his feed back would be appreciated by all on here, I have 2 ATBs waiting for me to fit them to my 90

looking forward to fitting mine got them just before a 20% price rise, I'm just waiting for some warm weather and a day or 2 away from a house renovation, although my def dosnt do much I just fancied them based on Tatras, Blackwolf and BP mans posts, basically a present too myself, I did do a lot of research and could not find any negative comments DEFENDER 90 TDCI XS,
I hope everyone is well and your land rovers make you happy |

It gets stuck...furthermore TC is useless on mud or snow. I drive often forest roads that are easy if dry, but really challenging when wet (clay type mud) or snowy. Then as steering is not always possible when road is nasty I often slede left or right, meaning the car is tilted to the side and only 2 wheels have traction, of course the wheels with no mass on them. Than you see how useless TC can be and I am always surprised about some "special" vocabulary than comes to mind in this situations.
I know atbs will be much help, but i'd rather leave the car in the field than eventually sacrifycing on road manner. Thats why my question is about on road behaviour of atb. |

I got stuck with MTs many times and each time because there was no grip left or right. But the main driver for upgrades is the reliability of the car. The idea is simple: each time I break sth. I put aftermarket stuff which is much stronger. Therefore my consideration regarding the front and rear dif- to replace them with stronger diffs and to upgrade the halfsfafts and flanges...but one at a time, this will ruin the family budget

I have had an ATB in the rear of mine and on road it been totally transparent. No negative affects at all. I fancy one for the front now.
Mine doesn't have traction control - I wish it did, ATB and TC are a marriage made in heaven. |

I don't have experience with ATB's, but have experience with ARB's, truetrac's and Detroit lockers.
In a side slope situation een open diff is the safest. Yes your highest tyre on the axle wil have the least grip and will spin but your lowest tyre will have grip and tries to prevent you from sliding down the hill. Any traction device that will try to any torque to the lower tyre will make the lower tyre spin to and you will slide down. 
I know I have experience with that.  Click image to enlarge Click image to enlarge  Roel

My defender is not going to be a trail vehicle and I dont go offroading for the sport...I just have to pass some forest roads for a purpose, and I dont take the defender if my jeep is available. I am not new to offroading, but new to defenders...have mine for two years now. bought it for long trips with the family, kids love it, so do my wife and I. I didnt want to make serious upgrades to it but I have to, because this vehicle is a bad quality. I started with that puma engine as my turbo died at 50k km...EGR flyed away, cat followed it. Then it was the output shaft of the gearbox, then the center diff...as you can see I work my way down to the diffs and they will be replaced soon together with the halh shafts and drive flanges, wich are badly worn too. And if LR part dies, defender has now 75k on theclock,I defenitely wont bye another from LR. So, soon I will be replacing this diffs, just doing my research what other people choose. I already have experience with arb in my jeep, they are strong design but dont want them for the defender because of the trouble I had with air leaks in the past.
