Do you think it was a bad sign ?

One front wheel going forwards and one backwards as my van was pulled onto recovery vehicle.

Reason for recovery, came to an abrupt halt whilst slowing for traffic lights in Sheffield city center this afternoon, said halt was accompanied by crunchy noises from gearbox and screechy noises from tyres.

I think its broke.

I think its broke too!

I think your assessment is correct

mash up


Richard Quinn - 3/1/10 at 09:22 PM

Yeah, you know what's happened don't you? ...







You've broken it!


JoelP - 3/1/10 at 09:22 PM

at least the diff still works!

not a vivaro is it?!

Jon i think the word your looking for is "lunched"


Jon Ison - 3/1/10 at 09:27 PM

But maybe the diff is ok ?

Why would the wheels turn in opposite direction ? I understand how it happens when jacked up and you spin one the other can rotate opposite direction but when the full weight is on and basically its been towed ?

It was jammed in gear btw, engine would start/run with clutch depressed but stall instantly clutch engaged.

I guess its broke good ?

Petrol non gearbox munching model though, allegedly.

there's your answer. jammed gearbox.

spider gears are turning the wheel opposite directions because the 'crown wheel' is jammed, would be the RWD way of thinking

If the diff crown wheel is locked solid, if you turn one wheel the only way it can spin is by rotating the other one backwards. So something in the drive train is properly borked.

when my super long life, quality engineered, high durability vivaro gear box broke, it was actually just the selector. I was stuck in 2nd for a week!

It really annoyed me that i spent about £500 on a new box when i bet it was something dead simple to repair.


JoelP - 3/1/10 at 09:42 PM

if the selector was broke, then it could either be stuck in a high gear, which might stall it, or more likely stuck in two gears at once, which would defiantely stall it.


Jon Ison - 3/1/10 at 09:43 PM

think is a bit more serious than that, somethings broke and locked everything up good n proper, just glad I was doing about 20mph coasting to a set of lights, I had traveled to Sheff on M1 but decided to come back on A roads, would not have liked a instant unexpected front wheel lock up at 70mph.......

eta two gears sound possible but I wasn't changing gear at the time of implosion, bottom line its fcuk'd

Surely if one wheel goes one way and one goes the other, it's the diff that's mangled? No matter as it's presumably all part of the gearbox in your daily driver, just like it is in mine. You'll either be dismantling the gearbox or just replacing it then.

wheels going opposite directions implies diff spider gears are fine, but the crownwheel cannot turn - wheel with least grip will spin backwards to allow the grippy wheel to roll forward with the road. So if the crown cannot turn its probably the main gears holding it still.
