Re: Advice Requested / Front Lower Control Arms

[Ambitious1]

I would like to ask for some advice. I will be replacing the front lower control arms on my MM since the bushings seem to be deteriorating. When I have replaced other parts like the rear control arms, watts link, sway bars and end links, I went with Metco, Addco and Moog. What are the best options for the front lower control arms? OEM or is there an improved better quality aftermarket option like Moog? Has anyone simply replaced the bushings? What is your experience? Thank you in advance.

I replaced the lower ball joints on mine a few years ago with Moog. Better quality than most other brands and have held up well. I’ve never heard of an aftermarket control arm option for the front of our cars.

The rear bushings can be found on eBay. Make sure the listing says "Big Hole". Those are bolt on. The front bushings can be replaced using a ball joint press. I have a snap on, not sure if the China presses will work?

Back-in-day, FoMoCo did not recommend replacing the balls. reason: Due to the pressure necessary to press the ball joints in/out, stress cracks could(?) occur in the aluminum control arms. *And yes, I know several have done it.

Excerpted from the MOOG installation instructions...


Examine ball joint contact area of the arm and make sure it is clean and free of cracks.

Failure to replace a cracked or damaged control arm may cause loss of steering ability because the CONTROL ARM MAY BREAK and cause the wheel to separate from the vehicle.

I replaced my upper and lowers last year with Moog. I found that the upper control arms are slightly larger in diameter and the plastic clips that hold the ABS cables no longer fit.

I read on here that someone that used Moog broke either the upper or lower ball joint bolt and decided to replace everything with Motorcraft. I run several Auto-Cross events each year and so far so good.

Here's what I ordered.

Moog-RK80038 Front Upper Control Arm And Ball Joint - Passenger Side
Moog-RK80040 Front Upper Control Arm And Ball Joint - Driver Side
Moog-RK80396 Front Lower Control Arm And Ball Joint - Driver Side
Moog-RK80395 Front Lower Control Arm And Ball Joint - Passenger Side

I'd also order new sway bar links and outer tie rod ends.
