Dex210 ball diff spring length? Different lengths?

[southern racer]

Hi

Does anyone know if Durango have purposefully changed the length of the spring in the ball diff in the Dex210?

Just building one and noticed the diff spring I have looks a couple of coils longer than the manual pics and some photos online. When fitted it, and adjusted to correct tension, it results in the nut sitting not that far down the outdrive slot. This means the dogbone end sits fairly shallow on that side in the outdrive and means it binds slightly on suspension travel as the dog bone end rubs on the plastic nut housing.

Have checked the diff build carefully and all seems correct, just the spring seems too long?

Is this a known issue? Have I got the wrong spring in my kit?

Shame as other than this the kit has been enjoyable to build (known printed manual
errors aside).

Many thanks in advance.
