So this replaces the threaded part on the end of the of the shock shaft. Your still using the proline spring perches?

Those appear to be Revo spring retainers.

Yes, indeed. the spring retainers.

Ah, I think I had it backwards, you mean this

Yeah, that's it.

it works like a charm on mine.

So what do you think about the traxxas cvd's I linked to.....that $ sounds to good to not try em out. I know there backordered though.

I noticed if I rotate the either rear wheel while holding the truck it will turn the motors and the front wheels, but if I rotate either of the front wheels only the other wheel will turn, not the motors or the rears. Why is this. I did notice while running the truck it seemed like the fronts wern't pulling real well, almost like it was rear wheel drive. I know my slipper is loose. Is there something in the diff that wears out causing this or is this normal?

if the shocks are still on, rubbing the shafts, take them off, and test again. my diffs felt locked with the shocks pushing the shafts to one side.

Yes, the stock shocks are on it and there is no rubbing. So that eliminates that. Are the diffs adjustable? Its obvious that the rears have more bite than the front. It may have been like this all along I don't know, but I'm noticing it now.

No, there not adjustable. Can you turn the left rear while holding the right rear? If not, then you have a locker in the rear. They don't handle all that great.

Your rear diff could be going bad and binding. Does the rear have a spool in it?
The rear has more traction for it gets more weight transferred to it.
Unless you have a center diff though. The front and rear should spin at the
same rate or speed.

All the drive line is stock emaxx, Im not sure how the truck is set up.

Try turning the gears by hand- all 4 wheels should turn in the ame direction. If the front doesnt do much then the front diff may be stripped. Also try turning both the front wheels in the same direction and at the same time- the motors and rears should turn too. If not then the front is definately stripped/ on its way out.

Well to complicate matters I hit a tree today and busted a front bulk and the front skid plate. What shoud be my replacement strategy?

If you are wanting to save up for hybrids id get the grey bulks for temporary replacement. If you arent getting hybrids than the FLM bulks are a nice buy.
