rwd gear box

[SUBRMN]

so ive read the above topic on rwd a 4wd box very easy to understand im gona try it out but just a few questions on the subject

am i able to fully remove front diff or is that a absolute nono?

and can i remove front axle stubs if i cant remove front diff without opening the box up to weld stub axle holes shut?

any help would be apreciated cheers

[DRFVDR]

well you could do all that BUT then you may find getting it WOFed without a cert an issue

[rex-leggy]

the way mines done avoids the cert issue sort of...... the crown wheel in the center diff is removed so no drive gets to the front diff , front axles can stay in and in a visual way it still looks 4wd .

the center diff is still welded.

dont know how it handles as im yet to drive it, some people say the way its been done is bad because the crown wheel plays a big part in the trans oil flow.

i dont think you have to weld the axle holes shut either.

I have the front diff removed, no driveshafts, and to block the holes where the axle stubs used to be I used brass frost plugs which you get from repco.

I reckon it looks factory like that, and thts how il be taking it for a wof, its had 2 previous wofs like that and not dodgey ones.

Oh and in rwd form my car drives completely different, not in a bad way, just gotta change your driving style.

My brother converted the rs when he had it. I've had it up on a hoist and the front axles have been removed and both sides have been capped. Can get more info/pics when i see him later this week. Havnt had any issues with getting warrants.

if you never plan to change it back to 4wd the i see no reason why you cant do that

[petrolheadjman]

Just find frost plugs that are the right diameter to blank off the holes instead of welding.

there is no problem with removing the crown wheel, leave pinion as is (Helps lubrication that is lost by removing crown) .As has been advised ,two frost plugs will blank off holes.

You should have a cert for this mod to be strictly legal.

Why peeps do this is still a mystery to me!! However each to their own too i say!

Yes you can, my front diff is removed completely, left pinion as is. you will have to split the gearbox open of course.

I like to overfill my gearbox to be on the safe side though.

Not sure exactly, just fill on dipstick then go another half a litre.

I think mine holds around 5litres at the moment, factory is 4litres, but u hav to fill the space the front diff used to occupy, then a bit more.
