Best way to rebuild front suspension

I want to replace the control arms and all in my front end and wanted some input on whether to use bushings or go with metal rod ends and adjustable arms, etc. Same for the rear in the near future. My car is a 2008 GT with 76000 miles and I do not track it, but I do engage in some spirited driving. I want something dependable that I won't have to replace in the next 7-10 years if I keep the car that long. I do not want to go back with stock replacement stuff and go thru the same thing again, but am unsure if I need to get spherical rod ends either. Looking for some input from those who have been thru this. Thanks.
Nick

Would do a thorough suspension check prior to replacing any parts other than those known to wear prematurely/are already problematic.
Many aftermarket pieces tend to have both great durability and longevity. Good luck

Mmm, I don't know if you'll be able to work out some adjustable control arms. They are kinda vehicle specific things with specific geometry.

Stock arms are the worst. The ball in the joint is un-polished, The wear surface is Nylon and no way to lube them. They wear the quickest. The big bushing in the Caster arm is mushy and filled with Dec-cool. Doesn't improve handling. Moog and Dorman also have plastic lined ball joints , but solid rubber bushings. Minor improvement, but not by much.
The Mevotech arms have the bronze bushings in the joint and are greasable. The ball is also polished and coated for rust prevention. Also solid rubber bushings that improve the steering response and handling. Yes you have to take the time to grease them 2 or 3 times a year. Only downside there is.


OR you can upgrade your front suspension components to Camaro control arms knuckles and struts. You will find the saved link at the top of the page.

That's good info on the Mevotech arms. I would have leaned towards Moog.

Suspension help update???

Thanks for the replies. I have already read thru the posts that are referenced and followed the directions on checking the front end play. My LCA and radius rod have loose ball joints so I just figured I would do it all at once and be done with it, especially since I am doing new Konis and Eibach springs all around. Thanks for the info on the Mevotech stuff, I was leaning that way. One big question I have is on the radius rod. I read somewhere about the bushing needing to be clocked with the car on the ground and then tightened up. That sounds almost like an impossible task, but I know to put the car on ramps and bounce the suspension. But, I read somewhere about some bushings that didn't need to be clocked because they were basically free floating. Any info or help on that? Is there a complete arm available with that already set up with that bushing? If not, I would have to buy the Mevotech and press the bushing out and press in the free floating one. Not sure who makes it, though.

I always torque suspension components with it "loaded". Take your jack, put it under the the ball joint in the LCA and then pump it up until the car just barely comes off whatever you're using for stands.
