Update #2 for tonight. Front and rear F10 Portal axle swapped over from the stock VP chassis to RPRC chassis. Looks like an easy process, but the front axle caused a ton of grief!:evil: The rear axle installed easy peasy! All of the titanium upper and lower links are a direct swap with no adjustment needed.
Most of the frustration on installing the front axle was the clearance for the servo horn and panhard link at the panhard mount. I always run a VP 20mm servo horn on all of my VP rigs with no problem. In fact, VP recommends the 20mm for the steering servo horn. Not the case for this though. I could not get enough throw out of the servo to the left without running into the panhard mount on the chassis. To get the throw needed to turn left, a 24mm long servo is needed.
At the moment I do not have any VP 24mm horns in my stock so I had to use an Amazon special that came with a cheapy servo I've purchased in the past. It gives the right amount of throw, but it wouldn't clear the Element servo plate or chassis rails. As seen below, I has to grind, cut and file to give enough clearance for full steer left and right. Not pretty, but It'll do for now!
Forgot to mention and add a pic, but I had to add 3mm spacers under the 3Bros servo to space it up so that the servo horn was high enough to clear the panhard mount at full left steer.
Onto the panhard link. It was coming in contact with the big a$$ servo horn when under full compression. I had a spare Traxxas TRX-4 bent rod end in my spare parts bin. Installed and it gave just enough drop to clear the servo horn.
I had to use an SSD 4mm rod end spacer to each of the panhard link and steering link to shift the axle over to the passenger side. The axle was slightly shifted to the driver side with the stock link setup. By adding the SSD spacers, the axle sits dead center under the chassis rails at ride height.
And here's a few front and rear pics.
More on the way shortly!
