Cracked front lower rear bushings can be replaced as follows:

Removal - jack front side to be changed & remove wheel, be sure to use jack stands for safety. Remove two lower ball joint bolts, bushing through bolt & front assembly bolt & nut. Loosen remaining three tie bar bolts to permit removal of lower control arm. Drive screw driver under bushing flange & ply to crack plastice flange away - this will permit exposure of bushed member for pressing out. Use #3 Pressing disk from SPX Volvo Tool #9995567 or make (this disk has 2.676" OD x 0.473" thick w/ 0.030 chamfers). I used a large vice & steel blocks to permit press-out.

Installation - scrape control arm bushing bore w/ knife followed by sandpaper & steel wool and apply a thin coat of Vasoline. Use metal oil filter wrench that fits Purolator L14459 (PER 4459) filter. This wrench Fits bushing flange nicely and transmits the force required for pressing home w/o cracking plastice flange. Installation of control arm is the opposite of removal above.

Ref. dimensions: Control arm bushing bore = 2.767" ID, Bushing Flange OD = 3.34", Bushing insertion OD = 2.833"

Time: approx. two hours per side
