Fitting, removing tapered joints
What, if anything do others use when asembling tapered joints such as those on track rod ends and bottom ball joints to make them easier to take
apart. I have used copper slip in the past but is anything else worth using thats better?

Use nothing. They are like that for a reason! Clean them thoroughly boefore assembly and they'll come apart easy enough. It's the grit,
dirt and rust that gets in there that causes them to be stubborn.

The only way to make them easier to take apart is to allow sufficient angle to get a good swing with a BFH and also have a range of BFH available to
take said swing with. Why bugger about with the balljoint splitter cos you know your gonna shag the gaiter.

Its all about knowing where to beat hell out of with the BFH!! I have seen someone refit the locknut and hit hell out of it trying to force it out
with not a movement!! Hit at 90 degrees to the taper, on the arm itself, and its likely to pop free in no time. Amazed one chav when i was passing by
walking to town with that technique - only hit it the once after he struggled for over 15 mins!!

Never use anything on a taper, just clean with an oil solvent such as kerosene or WD40 and wipe wipe clean. To seperate either the two hammer
impact shock method or a suitable ball joint seperator. A suitable sized screw press type ball joint seperator won't damage the joint --
unlike the fork type which is hammered in.
The two hammer method is very simple, one hammer is held tight against the steering arm in line the the taper and the tother (ideally smaller)
hammer is used to strike a single blow from the diagonally opposite side. NB accross the diameter of the taper hole. The idea is that under the
impact shock tapered hole flexes for an instant rel;easings its grip on the male taper.

1/2 kg hammer should be enough and always with another hammer at the rear to take the shock -- using a bigger hammer won't help.
Alternately the right size and type of ball joint splitter won't normall tear the gaitor .

Yes, I agree with all that.
I was amazed when I learned of the two hammer method but I've found it works every time.

I personally avoid using a big hammer for this, I always use a ball joint splitter (screw type) and light hammer taps to get it to let go..
Anyway as said don't put anything on the taper.. The nut really only pulls the joint together, then the tapper holds it tight.. It would be a
weak joint if the tappers don't grab..
