It possible to do without the special tool but as beginner I would advise you invest in a ball joint splitter - long handle wedge type are the most suitable for this job.

Do an Ebay search on ---- Silverline 300 x 20mm Ball Joint Separator

This is the quick and easy way -- not doing a proper race car style geometry adjustment but it should help you get the job done.

Before removing the ball joint (Transit drag ink) slacken the half locking nut on the thread shank by a couple of turns, then remove the nyloc nut on the balljoint tapered pi..
The hammer the wedge of the tool between the ball joint pin and the upright (swivlw hub) it should come out with a bang.

Count the number of turns as you unscrew the shank of the ball joint from the wishbone transfer the locking half nut nut over the screw the new balljoint into the wishbone the same number of turns . On the new balljoint wipe any gease or oil off the tapered pin and make sure the hole it goes into is dirt free before you push it home. Now apply while light downward pressure to force the tapered part into its hole fit the nut and (at this stage) lightly tighten it enough to pull fully hom e and snug.

Now replace the wheel drop the car off the jack and push it bak and forwards a metre or so -- look the front wheels with the steering straight ahead if the wheel look approximately the same angle to the road surface the camber angle is close enough for the vehicle to be safe to drive. If the angle of the wheel to the road surface dosen't look right get back to us and we will help you set the camber.

Now you can tighten the two nuts up making sure the top ball joint is sitting at a sensible angle not twisted relative to the wishbone --- the nuts need to be tight but don't overdo it.

After a short run as you are a novice mechanic it would be be best to check the nuts for tightness again.

On the indy you can remove the tube that the ball joint bolts though by removing the 12mm pinch bolt then unscrew the ball joint from the wish bone / that way you can undo the ball joint from inside the tube with a socket and punch the joint out with a punch

Some times there is a second bolt holding the tube in place SVA / IVA requirement

Many thanks all,

Measured the disance between the wishbone thread and the middle of the old drag link a coupld of times, undid the bolt in the hub, and knocked the old drag link out. popped in the new drag link, threaded it in till gap between middle of ball joint and wishbone was as before and bolted it all back together. jobs a good un.

many thanks
