Radius Arm Bushings
I've DOne This On Both My Trucks, A 91' XLT and A 93' XLT.
Depending On The Condition Of Your Suspension (rusty bolts...etc), You Might Wanna Take It To a Mechanic. It's Only Like 100.00 For Them To Do It And Saves The Hassle And Headache. Alot Of The Nuts Are Hard As Hell To Get Off On The Axle Side. Which Is The Recommended Way To Do It By Ford.
WAY ONE
You Need To Disconnect The Springs And Stud Bolts From The Axle On A 4WD. Remove The Control Arm From The Axle. Remove The Shock, Which Is All A PITA. Then Remove The Two Large Nuts On The End And Pull It Through.
WAY TWO
If You Go For The Removal Of The Crossmember, There Should Be Two Rivets On Either Side Of The Crossmember, If You See Them, It's Never Been Removed. If There Are 4-5 Bolts With Nuts On Either Side, It's Been Changed. You Can Drill The Out Or Sawzall Them, But Mark The crossmember Placement Before You Start. Just Replace The Rivets With Strong Bolts Of M10 Or Higher To Be Safe.
The Two Big Bolts, At The End Or The Arms, Which Are Normally 1 1/8 socket Size, Need To Be Removed No Matter What. And There Is A Heat Cover Over The Passenger Side's Bushings Due To Heat From The Cat. Make Sure That Shield Goes Back On. In My Experience The Axle Studs And Spring Bracket Nut Are Same Size. You Can Get The Bushing Sets For Around 10.00 a piece At Most Autoparts Stores. If You Remove The Crossmember, It's Easiest.
