mot brake rollers?

[missmouse]

Still more differing opinions!

I cant for the life of me see WHAT damage can occur to the torsen.
The whole idea of the differential speed gear ( that is its complete name) on any car, 2wd 0r 4wd, is to allow the wheels to turn at different speeds without causing damage!
This allows the car to go round corners!!!
There may be some questions arise with some of the newer cars that utilise viscouse couplings etc but a wholly ( wholey?) mechanical system I cant see in what way this COULD be damaged? Perhaps somebody could enlighten me as to what component inside the differential will actually break & WHY?
No urban myths please just hard mechanical facts.

On a slightly related note, I never understand why some people say you cant tow a 4x4 even if all 4 wheels are on the floor?!

yep!

IF a brake roller has broken a diff it will be one of two reasons. The diff was fooked anyway, seriously fooked or the diff was locked and the car strapped down so it couldn't come off rollers

as for pipes and hoses bursting... Do you blame the mot tester for that?! I'd rather they burt on rollers than when you stomp on the brakes when a child walks out infront of you!

You can tow a 4x4 no worries. If it is suspended you need to use a dolly on rear

if a brake roller doing not enough speed to register on a speedo could brake the diff, why does the diff handle what, 700 bhp... And what do you think the diff is doing when an inside front is spinning?

Lastly, if an mot test blows a head gasket, me thinks it was on it's way out anyway!

Don't you mean tow on a dolly trailer?

I thought towing with all 4 wheels on the gound was OK to do?
