Transmission/dogbones popping

[Edvin]

I recently got a savage x 4.6 running. Today I was running the car just tuning the engine.

It ran fine but when I was finished and spun the wheels by hand I noticed it would click and the wheels would be hard to turn.

There is a tiny bit of metal debris inside of the transmission which might be a clue and the sound is coming from the transmission.

The entire upper assembly of the transmission has been removed and it only clicks when the car is moving forward.

Edit: Found the problem, it’s the cup the dogbone connects to where the brakediscs mount. Does anyone know if there is any upgrade available for this specific cup?

Thats is already a beefy part. So with that part out there is no clicking? Usually click comes from the diffs.

To me it seems like the cup for the metal discbrakes. The newer fiberglass discs have way beefier cups (although I'm not sure if the metal is harder or not). And actually there is a conversion set (#87025) with new discs cups screws and all (I recently had to do the conversion as there are no brakepads available for the old metal discs).
These might worth a try.
