Possible axle knuckle or yoke question
« on: June 16, 2016, 08:02:55 am »
Hi everyone, this is my first time posting here so if in doing anything wrong please let me know. Recently I purchased a 1977 gmc k10 and have been doing some work to it.

I wanted to do a quick rotor and brake change but did not know how much work was involved. Anyway, I'm having trouble figuring out what I need, or the name of the part I'm looking it. The picture is attached below



I believe it is the yoke and the larger part connected to the hub is the knuckle? I noticed one of the rubber seals or maybe bushing was ripped apart, I tried to show it best in the picture.
If anyone knows what part or parts kit I need, it would be greatly appreciated. Thanks!

that would be a lower ball joint. you dont have to change them to change the rotors. we do have a write up that may help

The reason I'm changing it is because of the tear in that rubber piece

Does it make a difference if the axle is a Dana 44, don't they have kingpins instead of ball joints?

afaik only the dana 60 would have a kingpin. never seen a 44 with the kingpin. that one link is a 2wd so its a slightly different setup but its pretty much the same setup

Okay thank you for the info, it looks pretty straightforward. I figured while I have everything off I might as well replace it now.

Ok, it looks like this would be the correct one? The one with the red arrow. I'll have to check them when I get home

i would go with the 371 due to the fact no fitting. the hole for the fitting some tend to think it makes a weak spot for them to break. i cant verify this but ive heard more than one person talk about it even the off road tv shows

Under normal operating conditions the hole for the grease fitting will not make a bit of difference.
It'd be nice if the joints could be had with low profile fittings in the caps.

ive seen them have a screw to remove then you have to put a zerk fitting in it when you want to grease. i think thats the style from moog

This is a joint from MOOG. It has a grease fitting installed that requires filling with a needle.
