Steering issues HELP!

[Man Bear Pig]

Having trouble with my NH.. Jaked it up hard and keep braking shit.. On my 3rd idler arm ... ive now dropped a steering box( i can see about 5-10 mm of splines exposed out the dottom of the steering box..

I realise i need to lower the front to reduce the angle and strain.. Is anyone else having this trouble and how did u solve it ?
Need it solved and reliable asap !
