No. No matter what you do, you'll never get the same caliber of seal with the aftermarket inner tie rods unless you do something crazy, like glue the end of the boot to the tie rod and cake RTV on it.
I see this problem a fair amount on the trail.
Everything is fine, then the driver hits a shallow puddle and the dash lights light up like a Christmas tree. sometimes you can clean it, try to reseal it and get it to come back to life by clearing the KAM, sometimes not.
As a previous poster stated, The SVC tie rod design retains the factory inners and maintains the seal.
And FYI- The steering rack SHOULD be about $1100 after the core return. It is literally 8 bolts and 2 plugs to swap it and it takes 20 mins.
It takes way longer to do the alignment and re-initialization of the rack than it does to swap the physical rack.
I know this because the EPAS rack is one of those lovely bits that I've had to replace.
Ford just released a superseding master rack part number that ends in N. Make sure that they aren't giving you something older and don't be tempted to buy an eBay rack bc they are $500 on there. the wrong PN will work mechanically, but the computer will fail the recalibration/re-initialization.
