Welded diff - legal for road use?
Discussion
Bit of a debate - is fitting a welded diff to a road car legal? Car passed MOT with the welded diff fitted (advisory given for having a welded diff) and the diff is also down on the modifications list with the insurer specifically noted as 'welded diff'.
If this is not legal, what offence would you be committing? Google sheds no light...

The police had no issues with welded diffs fitted to any of my old cars. Nothing illegal about a locked diff, only if you are drifting, or driving without due care etc etc on public highways.
The actual driving isn't an issue, just how you behave with it. Otherwise lorries using difflocks on steep hills etc, surely that would make them illegal?

Not sure why you'd want a car that didn't go round corners though?

Can't see a C&U offence, but every urban roundabout might raise sufficient eyebrows for either a s59, careless driving, or even dangerous.
They don't do anything different during 'normal driving'. They just skip the inside wheel during very tight turns, such as parking or U-turns.motco said:
I believe the Daf Daffodil had a solid axle (no diff). If one of the drive belts broke it was possible to drive on one.
Think you are sort of wrong. There was no differential in a Daf, but neither is the back axle solid either. The two rear wheels are each driven by a separate belt and pulleys. Quite delightful really but very confusing to watch one accelerate with a floored throttle. You are right however in saying you can drive home on one belt - with one wheel drive!

No idea as to legality, but the last car I know of that was made with no differential was the chain gang Frazer Nash of the 30s.
Nash and Godfrey hated cogsmade a car with chains and dogs
it worked but I wonder would it if
they have made it with a diff?
