I am having a pain in the a!! time trying to get the tie rod ends of. Is there a easy way to get them off cause it is hard to turn means I cant turn them. What place or company sells them for real cheap.

 

One end of the tierod has reverse treads. You will need a 19 and a 17mm wrench to get them lose. When you do get one to turn, the other 3 nuts will all turn the same way if you don't have the complete tierod on the quad backwards.
The 400 tierods will fit on the 250, but they are not as good of quality as the 250 ones. We are using the R ones because they are stronger. It is cheaper to buy the tierod with the ends as a set than just buying each part.
The part on the rod that uses the 10mm wrench to turn the rod goes to the outside, if you want to put it on the correct way.
