So i got a good deal on a pair of T.F flex arms. I'm doing the install and have a few issues. first i don't know which way the front upper zerk fittings are suppose to face.. i assume pointing down at the ground. i also don't know how the other end is suppose to mount to axle. it looks like a toning fork and the face side is flat and the down side goes up on a angle. also i heard that they can be used to adjust the caster (for that i don't have the front lowers yet) and when i made the arms as small as possible, they were about a quarter of an inch or more small than stock. isn't it suppose to be smaller than stock if i wanted to adj. the caster...?

also with the rear i don't know which end of the flex arm mounts into what. the install instructions off the site are not to specific on these pairs. any one with knowledge of these arms, plz chime in!

 

Rear lower, flex joint axle end. Front uppers , grease zert down is fine, the other end really doesn't matter. Shorter than stock will cause the pinion to go down. Just set them to stock length and let the shop set your caster.
