Welded Diff- Will It Pass?

[Guest Joe_burtenshaw]

Hi guys my differential is welded in my 2b, does that affect the iva? Many thanks joe

It would probably be picked up on the brake tester and would most likely fail becuase it's not safe to drive on the road.

[Guest Ian & Carole]

It will fail IVA as they do side to side individual brake tests followed by axle test.

 

Obviously you have never driven a welded diff on dry tarmac, even worse in wet!!!! :80: or bought tyres as you will wear them out very very quickly.

 

Can I ask why you have fitted a welded diff ??

I used to run welded diffs in my bangers & hot rods.

Obviously we ran on shale & they were great for kicking the rear end out

on a loose surface.....but I tried one on a tarmac surface....just once...never again.

LETHAL.

[Guest shaggy]

Horrible on tarmac

bought one for the cobra - didn't know till I fitted it............

Fit a Sierra LSD for IVA and you'll be ok

[Guest Nik]

I would guess it would either throw the car outta the rollers or break a shaft when they try to lock one side at a time!

[Guest Joe_burtenshaw]

Thanks guys! Glad I asked! What I have at the moment is a lexus is300 engine and rear diff, but it isn't an LSD, so will a sierra diff work and hold the power? Or does anyone else know of a suitable LSD? Many thanks joe

The Sierra diffs are pretty strong, & theres an LSD version fitted to the 4x4 & Cosworths.

Most common ratio is 3.6, there was a 3.38 (IIRC) but theyre like hens teeth.

What ratio is the Lexus? I suspect it will be pretty low .

IIRC you fitted the whole Lexus rear end?

You may be better to source a standard Lexus diff.

You'll be a pathfinder fitting a Sierra diff in a Lexus frame
