You've all probably seen the notice from Houston regarding the new, re-engineered lower ball joints. They are also only $25.00 This comes at a great time because I may have to do mine. (I'm still investigating) I asked James if I'd need the reinforcement collar with theirs. He stated that I could still have a fit problem if the control arm deforms. He also told me that Houston doesn't sell a collar kit because it's a legal liability and a safety issue. At this point I'm thinking "Why don't I just order a new control arm?" Ahhhhhh....neither Houston, nor PJ Grady sell them. They -appear- unavailable. If I liberated one from a wrecked/parts car, I would likely face the same issue of metal fatigue and a poor fit so what's the point? This brings me back to the collar kit. Grady's site makes it seem like a very simple install. Comes with instructions. How difficult is it to install this collar? Is it really the big safety issue Houston claims? Thanks, Rich #5335
