Okay start off this is a US ( im in Canada) truck not sure if it matters .Had fron ball joints on rf replaced 2 years ago less than 3000 miles since done .These were Moog ball joints ,last summer found that the right upper had popped up thru the axle so had it tacked in place like the old days then recently the lower ball joint started oblonging the knuckle to where the wheel was flopping .Had a used knuckle install and found that the last guy didnt install the clips that hold in the joint so would explain the top joint coming loose .Problem is new lower joint when pressed in as far as it would go it would not clear the groove to install the lock ring so this was tacked in .Could this have a 2500 or 3500 axle in it instead of a 1500 ???

 

replacement balljoints are oversized so they will enlarged the bore. if the replacements wear out, a new knuckle is required for most products. try another brand to see if they fit.

 

have a different brand now and like i said they dont press in deep enough to insert the lock ring ...

 

Are they seated all the way down?

The heavier duty trucks used a different front axle altogether, and were universally 8 lug....

 

they are pressed in as far as they can go but the knuckles 1500 2500 3500 up are the same so could have 6 bolt rim

 

Could check the numbers on the axle I suppose.

 

just need to know where to look ?> on the other hand i have an evap leak and i have found a vac line that connects to what appears to be a brake line union/block thats on the rear axle left side cant see where it use to connect and dont see it on any diagrams .??

 

That line sounds like the breather for the axle. It goes up to the bed or frame and should have a vent cap of some sort on the end of it.

 

theres a little plastic splitter/joiner something like this

that looks like it plugs into something else rubber and I was thinking tvent line maybe but never saw one come off a brake line union ???

 

The hose barb the vent line hooks to holds the junction block on the axle. It's actually a separate part.
