tie rod ends

If you want to do the outers, they're quite easy. The inners are more involved, and if the rack is older, it's often wise to get a reman'd rack with new inners already installed (it's been awhile since I priced inners, but many are expensive enough that a reman'd rack is more attractive).

Remember that you'll need an alignment afterwards, so if funds allow, replace anything you envision failing soon (to save another alignment cost).

Good luck.
 
when my car made that squeaking sound it was the ball joints going bad. i didnt know that at first so i changed the inner and outer tie rods and still had squeaking. i figured it out when the pass. side ball joint fell out. ford calls the ball joints and tie rods maintenance free, no grease fittings, and and that the squeaking is the indicator to replace them. may be a good idea to replace them all while your at it, luckily i was stopping at a light when mine fell out or else it could have been a bad deal.
 
i just did my inners and outers recently.

Its a very easy job

the inners if i remember were 20-40 a peice and the outers were much cheaper.

Very very easy job, you just have to remove the pins....but that is cake with a pair of dikes and a chisel....

took me about 2 hours to do everything.
