Hey Chad. Got got my box cleaned out sorry about that lol.
Sorry to ruin your weekend as well, I do what I can.

Well I did the install myself both times, it's easy. It just kinda sucks because in theory an alignment after the install would be a good idea. I changed both rear arms and a front UBJ, so I had three corners of the car unhooked and I still haven't gotten an alignment yet...that was about 5K miles ago lol.
For the install, you just need basic hand tools. Not suprising in our climate, the ball joints like to stick. I used to fight ball joints with banging, prying, etc, but about a year ago I got a ball joint removal tool (the type with a hinge and screw) and it makes quick work of any ball joint. Technically you are supposed to tighten the inboard bolt with the wheel on the ground to avoid preloading the bushing, but screw that unless you have a lift...I can't get access like that on my car, so I've tightened it to spec both times with the car jacked up, no biggie. Hell, it's the ball joint we are worried about, not that bushing.
I've thought about the fact that the lower arm replacements might help bring the tire more inboard to help reduce rubbing, that would be a nice advantage. What kind of prices are you seeing for the Ingalls rear arms?
Ingalls hooked me up big time on my front UBJ that I needed to replace. Mine was shot and I needed a replacement, but you can't get the UBJ without buying the whole damn arm...at least I never found it after searching like crazy. Luckily someone pointed me to Ingalls because they make a UBJ replacement for their front upper arm camber kit, which happens to re-use the stock ball joint, hence making their ball joint an oem replacement. $20 or so and I was golden...the OEM arm is a LOT more lol.
