Upper ball joint removal / UCA advise

[UrbanRage]

 

The truck was leveled with 5100s over a 100K miles ago, and it’s time to replace them. I figured I would try something different and purchased the Eibach adjustable coilovers. I’ve been told by Shock Surplus as long the lift isn’t much higher than level, there will be no issues with the factory control arms and ball joints. So this weekend, I was going to install them, but I couldn’t separate the upper control arm from the steering knuckle without damaging the ball joint boot. I decided to put the tires back on and keep going on the 5100s for now. The ball joints are still tight, and the boots are in good shape.

 

- Looking for advise on separating the upper control arms without damaging the boot. I tired the usual hitting the knuckle with a hammer and the separator I have didn't fit. I wasn't whaling on the knuckle with hammer, but they weren't little taps either.  

- Has anyone used the replacement ball joint boots on Amazon? If so, which ones and have they held up?

- Would it be smart to replace the upper control arms? If so any recommendations?

I’m hoping someone with Eibach’s can chime in, but either way, I know there is a lot smart people here that will have good advise. 

I appreciate your advise.

Jack the truck up, tire off, loosen the bj nut to the last few threads and smack the spindle with a mallet or hammer right at the bj. It will separate. 

 

The lower is the same, but set the truck on jack stands and put a jack under the lower control arm and jack up the lower to aid in separation.

 

Little more umph then this guy.

Lastly having rebult my front end twice now, I'd highly suggest replacing the uppers. Given you have the ability to go more then 2". I'd suggest connito or a control arm that states it corrects angles of lifted suspensions
