’94 K2500 HD (8 lug hubs)

[GregAbell]

Anybody with a ’94 K2500 HD (8 lug hubs) care to take a look at your upper A-Arm for me?

Is the upper ball joint mounted above or below the A-Arm? Also, is the brake hose clamp mounted towards the front of the truck or the rear?

I could of sworn that mine was mounted below (before disassembly), but the Service Manual shows it mounting on the top side.

Thanks!

The ball joint is mounted under the A-arm. I don't think it would even work the other way. The brake hose forward, front. The hose won't reach if you clamp it rear.

just look at your other side.

I think they mount on top of the A frame.

I pulled both sides already so I could press-in new bushings

Well, the new Moog upper ball joints will not mount on the top side of the A-arm (I checked the AutoZone ones, and they would mount on the top). Supposedly the AutoZone ones match up to the Moog part number ones (but they appear to be smaller).

When the Moog parts are mounted to the bottom side, when you lower the A-Arm (to where the A-Arm hits the stop), the distance between the shock mounting points appears to be about an inch short. That doesn't sound right - to have the shock act as the full extension suspension stop.

Do I run back to AutoZone and purchase their *smaller* ball joints, so that I can mount them on the top side? With them being smaller, I'm kind of hesitant.

you should be able to tell looking at the mating surface on the A frame and old joints what went where.

1500 and 2500 mounted on top, 3500 mounted from below. Some people flip their ball joints when they crank their bars way up.

Of course, strange things happen at the factory so who knows where yours were origionally. LOL

Under under underneath! I am looking at it as I type. 2500's underneath. won't even fit over top.
