All loaded up.



Got a set of used OEM upper control arms to save on time by pressing out the bushings and ball joints. Also gave me enough time to prep and paint it after new bushings and ball joints were installed.


This CUDA parts washer is amazing and am so grateful to be able to use it. The shop uses this on a daily basis to clean parts before reinstallation. Another reason I use Import Motor Werks in Cary, NC. Also the main reason being Matt, he is a very skilled master tech that I trust. Thanks Matt & Import Motor Werks who by the way did all the work while I tried to stay out of the way and try to work on small stuff around him while the truck was on the lift.


After a quick wash in the CUDA prepped and refinished the lower control arms as well.



Didn't get to take a lot of pictures during the actual work, game plan was to try to knock as much of this out in a day so the car is movable and not stuck on the lift.

Disassembled everything, during which I found out that the only thing keeping my power steering fluid in the rack were the boots. Removal of the inner tie rods required the removal of the steering rack boots which resulted in a healthy puking of power steering fluid out of both ends of the rack. I felt much better about replacing the rack and lines at this point, cause boy those parts weren't cheap.  


New rack, lines, inner and outer tie rods installed with all new hardware.





While I was working on replacing AHC globes and rear upper control arms Matt finished up the steering rack, diff seals, CV Axles, upper and lower shock bushings including the AHC line O-rings as well as the upper and lower control arms including the in-frame bushings. Look at how nice all these new parts look! I know I know, it's a truck but the process of bringing this truck back to OEM spec is something that really excites me. 




New AHC globes, bled and even replaced the bleed plugs and caps.




The rear shock bushings were a pain in the ass to say the least! The location is a pain to get to to undo the bolts, swapping out the O-rings once the line was off was not as bad though. If I was to do it again I would definitely use the location guide to cut out a hole in the floor board in the trunk to access the top of the shock. Matt got it done though, new bushings and O-rings complete!!




All this work ended up being over a course of two days. Day 1 was about 8 hours of continuous work not even stopping for lunch but got the whole front end and AHC globes replaced and bled. Day 2 was only about 3 hours which consisted of the rear end, bleeding the AHC again, verified the steering wheel and rack is centered, got an alignment and was on my merry way! The difference!! WOW!! Huge huge difference and this is before I baselined the pressures. That's for another day though. For now I'm just glad that all this work is done. A huge thanks to Matt and Import Motor Werks for taking this on!
