Matt:

I repalced the ball joints on my 745t earlier this year. Below is the description (the best I can remember) of how I did it.

1. Loosen lug nut on front wheels.

2. Set parking brake and block rear wheels. Raise car and support on jack

stands placed under subframe.

3. Remove wheels.

4. Remove cotter pin or retaining clip from threaded portion of ball

joint,loosen and remove large nut holding tie rod to ball joint.

5. Separate tie rod form ball joint using fork type pry bar. At this point

you will most likely need some type of long pry bar to push tie rod end

down far enough to remove it completely from the ball joint.

6. Loosen two bolts holding ball joint to lower strut tube.

7. Remove ball joint. A couple soft wacks with a rubber mallet might

be necessary to break the ball joint loose from the strut tower after

the two bolts have been removed.

8. Install new ball joint on strut tube using the bolts provided. Be sure

to use some lock tite on the threads. If I remember correctly, the MOOG

ball joint I purchased came with some red lock tite. Do not hold me to

this about the color. But use some. Torque bolts down to spec.

9. Use the long pry bar to push tie rod end down far enough so as to get it

back on the ball joint. Extra pair of hands could be helpful here.

10.Install new nut that holds tie rod onto ball joint and tighten to spec.

It will probably be necessary to use the long pry bar to push up on tie

rod end to prevent threaded portion of ball joint from spinning while

you are tightening the nut. Replace cotter pin or retaining clip.

11.Reinstall wheel, lower car and enjoy nice ride and steering.

12.Get front end aligned

Hope this helps and good luck.
