track rod and ball joint, why no grease
 
when refitting the track rod end and lower ball joint to the front "stub axle"
why is grease not used? These are moving joints and metal to metal.

thanks

It’s a tight taper fit so doesn’t move, only the ball joint in the cup moves and it’s loaded with grease

it moves in the rubber part at the bottom not at the bolt?

The boot is there to stop muck getting into the grease that lubes the ball/seat. There's just enough packed into the ball joint during manufacture to last it's normal service life. This will be shortened if the boot gets damaged. The tapered pin/'bolt' is the mounting and locking system. Tapers won't turn when tightened down.

thanks Les4048 and TC. I feel stupid, I really thought they turned at the bolt. I can relax as it's been bugging me this afternoon

fool of the week goes to me.

The next arms I fit, im going to drill and tap a hole and fit grease nipples to the ball joints, I can then see if they last any longer...

In the good old days a lot of components had grease points and a grease gun was part of your tool kit :}

No one is a fool by asking a question, no one can possibly know everything and I bet your question has answered something that many other wanted to know but were too frightened to ask.

For all the price they are is it really going to be worth the effort. I can see you doing it with your mechanical knowledge but if the man in the street tried it they could make a right mess of it. We have self tapping grease nipples which would make it easier after drilling an 1/8 hole

When I replaced my drop links I looked inside the rubbers and found they had barely any grease in them.
I packed as much grease as I could then refitted the rubber. Those drop links lasted a whole lot longer as a result.
