Thuren Rear Trackbar:
This is definitely in the top 5 of my most difficult mods/installs list. I knew it would be challenging going into it just from reading about other peoples experiences.
Despite the difficulty I have to hand it to Thuren, their manufacturing/construction is one of the best ive seen. The welds are almost like art:

Difficulties:
-Alignment: I had to loosen, tighten, take apart numerous times to get the hardware and mounting holes to align
-Space constraints: getting the hardware to torque specs was extremely difficult esp given the torque requirements (100-160lb/ft) this could have probably been easier if i had more specialize tools but most of my torque wrenches for those ranges are 1/2in and bullky which were hard to maneuver around. ***update: while doing my shock install i found it was easier access the hardware with the wheels off, instructions indicate wheels dont need to be removed. I should have done this from the start***
-Power wagons require drilling 9/16 hole, I wish there was a power wagon specific one that used existing mounting.
Couple of Tips:
-To get easier access to the oem passenger side bolt, use a ratchet strap

-To assist with bolt alignment of the bar to the mount, use a jack to lift the axle to shift the bar.
-Use a stepbit for enlarging hole vs drill bit
Here is a shot of the semi finished install (still waiting on a 9/16 drill bit to get to the rear of the mount)
Still havent got a chance to drive it around, but hoping the blood sweat and tears were worth it.
Happy Modding!
