LR UCA's
I finally got around to installing my Light Racing Upper Control Arms. This was a B**** of a project. I read all the posts from other installs so I was ready for a fight. My upper ball joints were also ready for a fight. About a year ago I noticed a tear in the boot of my upper ball joint. I'm not sure how long it had been there. Probably happened during the lift install or from too much droop on the trail. I could still see grease in there and there was no excess play so I put it off until now.
Torn UBJ boot:
There are lots of threads on the UBJ removal so I won't repeat.

The early steps are easy and go quickly. It's like when your playing pool and you make a couple shots in a row and you start struttin' around like you're gonna shark the whole bar, then you miss everything else. All goes well until you must press the UBJ from the steering spindle.
There is an SPC video on youtube showing the process on a Tacoma, though the UBJ's are different than our 3rd Gens. It shows a guy leisurely turning wrenches and removing bolts. This was not my experience. This was the aftermath after getting 1 UBJ seperated from the steering spindle
The combination that finally worked was the 3 Jaw puller with a homemade spacer of 1.75 tubing, and the top and bottom receiver pieces from the c-clamp ball joint press. Add a breaker bar, some yelling, a few cuss words and "Pow!" the ubj breaks free and slowly presses out of the spindle.
Fortunately the install of the new UCA's and ball joint is much much easier. Here is the finished product:
I got an alignment yesterday and I am happy with the results. The amount of information out there regarding the adjustment of Caster and Camber is dizzying. The front end feels much better. I assume much of this is likely due to the new bushings in the UCA and the return of caster. I noticed it immediately. I need to find a better alignment place though. Someone who has experience with non-factory, aftermarket parts, and specs. Basically, most places are trying to get you to factory specs. They put your truck on the rack, type in 99 4Runner and start trying. There is very little factory spec left on my truck. The guy basically wouldn't touch the UCA's and dialed everything in with the LCA's.
Sorry. I couldn't get my crappy cell phone pic to rotate.
I know there is tons of adjustability yet to be had and likely another degree of positive caster. I'm gonna roll with this for now, and it feels really good, but will likely knock it out of alignment with a few wheelin trips and then find a better shop. I spoke to SPC after the fact, and they basically said adjusting more caster at the UCA is fine, but will push the wheel back in the wheel well. I have no room for that. So, they said, set UCA caster to +2 degrees (where it is). Max out the caster at the LCA's and then dial in camber using the adjustment nut on top of the UCA's. This will move the wheel slightly forward rather than back. I literally couldn't sleep last night processing my crash course in alignment 101. Basically, I need to find a shop that will allow me to customize my alignment. The 'big-box' shops likely will not, as I found out.
Really happy with the UCA's! I'm adding limit straps tonight (already installed lower shock bolt, just need to weld in bracket and bolt in strap/clevis). Will use strap install from [MENTION=44220]BigFishAllDay[/MENTION] and [MENTION=67615]Dirtco[/MENTION] as a guide. Going offroad 2x in the next week and will update.
Thanks for checkin' in!
Oh, and yes, those are the 'super pimp' RCV CVJ axles. I installed those while I had everything torn out. That will be a separate write-up if I decide to keep them. So far the entire process has been a disaster. I'm not one to start ranting or throwing around negative reviews, but everything has been a challenge to say the least. I may be the first person to have ordered them (and at that price point I understand why). They have been very accomodating and said satisfaction guranteed, but we are not there yet. Will test them this week. Thanks!
