Delrin Rear Subframe Bushings
BK027 (Continued)
12. Support the rear subframe with a hydraulic jack.
13. Using Image 10 below as a reference, remove the (4) subframe mounting bolts using a 21mm socket.
14. Lower the rear subframe assembly down.
NOTE: It is possible, however more difficult, to remove the bushings without disassembling the rear
cradle. Removing the suspension, differential, axles, etc. from the cradle makes handling the cradle much
easier while removing the bushings. If you choose to leave the suspension and driveline in tact, proceed to
step #22, if you wish to disassemble the cradle, follow steps 15-21 first.
15. Using an 18mm socket and a 21mm socket, remove the upper A-arms.
16. Using an 18mm socket and a 21mm socket, remove the toe rods.
17. Using an 18mm socket, remove the lower shock bolts on the control arms.
18. Using an 18mm socket and a 21mm socket, remove the lower control arms.
19. Using an 18mm socket, remove the trailing arms.
20. At this point, the CV axles may be “popped” out of the differential and the outer spindle/hub/CV axle
assemblies can be removed.
21. Using an 18mm wrench and socket, loosen the (3) differential bolts and remove the differential.
22. Using a sawzall, insert the blade through the center aluminum sleeve of the bushing and cut all the way
through the sleeve and rubber, taking care not to damage the cradle. Most of the times one cut is
sufficient to knock the bushing out however it may require two cuts on some stubborn bushings.
23. Duplicate this procedure on all 4 mounting bushings.
