Hi Nikhil,

The 1 Piece FFRA are you sure its has a Left Off-Set, the picture is at an angle.

wrt the second pic, is the Axle marked by the red Arrow a 1 piece FFRA?

Arka

yes , after seeing pic i am not sure if it was one piece FFRA or with some left offset two piece FFRA.

but its used on 4x2 FC.

no, the arrowed one has right offset for the 4x4 FC.

one at the bottom has left offset so it must be for the 4x2 FC.

Hi Nikhil,

Are you sure the one marked by arrow is Right off-Set for a 4x4 FC.

From the rear it may look like a left off-set for a 4x2 FC.

Arka

yes,

if we rotate the arrowed axle to front in the same position, it becomes right offset used for 4x4 FC. (when we see it from the back)

Hi Nikhil,

If we rotate the Axle along axis of the Axle Tube then the Spring Saddle will get repositioned for SUA.

And the Differential will get flipped, hence unusable.

Please observe the position of the Spring Saddle and Brake Lines.

Arka

right.

so even 4x4 FC use a left offset axle??

how come??

the t18 has a out put to right & connection it to left offset axle will be not be a good idea.

Default Re: Difference in the track width of the mm 550 ngcs .

Arka the spring saddle can be re welded to the new location. If the axle is flipped and the diff becomes ulta, will it be not usable, i would like to learn on this subject.

IMHO & AFAIK it has some thing to do with the lubrication part ( will not be good for the pinion bearing lubrication )

also need to check if & how the direction of rotation of crown pinion affects performance ( or not )

I am not sure abt both the things , its just a thought -- you guys can think on it .

BTW something but about using the FC axles in moded ( upgraded engined ) Jeeps ---
I have observed that the longer axle in a off set diff setup always tends to break early ( compared to the shorter ) , now if the FC axles are used , is there any chance they will break easily because of the longer length ?? ( assuming they are of same material & treatment like the standard Jeep ) -just a thought again not sure abt it , May be experts can guide us further

Sudarshan
Hi Sandep,

When the diff is flipped, there are two Problems

1) As Sudarshan JEE mentioned there is insufficient lubrication for the Pinion Gear.

2) AFAIK The Direction of Rotation of the Differential Changes, so instead of going forward the vehicle will go reverse

Regards,

Arka

PS - So diffs do the 4WD FC Vans use?
