Good to know, Jason. Thanks!

ok..
Sounds good.
I want to think that it's as a result of the fab work that I had done earlier this year as everything was good before then, but if there is a problem, I'd like to find out what it is, get it addressed and try to get the X to be legal for at least a bit - just in case I could use it this winter if the snow is more than a little challenging

That might be the case Mike, if they had to relocate the evap canister
when they moved the tank.
Even a small leak will trip the CEL on.

Pretty much everything was moved... So, how can I check to see if there's a small leak that could trigger the CEL?

When you bring it up this weekend, we'll check the codes. Also, with the age of you truck, I would be surprised if one of those hoses to the evap canister wasn't cracked, particularly if they moved it. If it were me, I'd buy a length of hose and replace all of them.

that could be the plan of attack..

Evap leaks can be hard to pinpont and isolate
we have a evap system smoke machine at work
that supplies a smoke into the system to pinpoint a leak.

Like Scott said, check for the codes first, to see if it is a evap concern.
then a visual inspection may be all thats needed and the replacement of a cracked hose.
sometimes mud and water can enter the system due to a relocation
and stick a canister vent valve also.

I got the new hubs on and, while one of the hubs was definitely a problem, I now have another one that didn't manifest itself until both hubs work. I have a bad CV joint.

While it's not entirely blown, it snap, crackles and pops. Now, back to work.

This is done.

outstanding..Anything left to do in order to be ready for Saturday?

Just registration and inspection, which is probably not going to happen.
