Can you replace the lower ball joints in the control arms
I have a 1998 Ford Expedition, 4 wheel dr. 4.6 liter engine. I'm trying to change the lower ball joints in the control arms.
My question is, can you replace the ball joints seperate from the control arm?
I have two books , one says you can replace them seperatly, the other say's you have to replace the controls arms with the ball joints already pressed in them. Can you help?

The lower ball joint original is riveted into the lower control arm. If you can get to the lower control arm with a drill then the rivets can be drilled out and the joint removed . I find it quicker to remove the lower arm and do the job in a vice on the bench. Replacement ball joints will come with grade 8 bolts ( auto engineering quality) and will simply bolt into place using the holes for the rivets. So the procedure will be to jack the vehicle and place securely on jack stands. remove the wheel, remove the ball joint nut and using a ball joint removing tool drive the ball joint taper out of the support arm ( strut) Remove the inner pivot bolt ( remember to note the position of the lock washer as it is encentric and alters the wheel alignment) put the arm in a vice and carry on.
the lower ball joint is pressed into the lower control arm. You will need a ball joint press to remove and install the ball joint. The other option is to replace the lower control arm.
Some parts store will have presses for loan. You will have to check around and see if any in your area have these. If you can't find one you could always pull the control arm and bring it to a shop or machine shop and have them swap the ball joint.
Its a pretty simple procedure.
1. remove the wheel 2. remove the pinch bolt that secures the knuckle to the ball joint. 3. separate the lower control arm from the knuckle. 4. remove snap ring from the ball joint (if it has one) 5. use a ball joint press to press out the old ball joint. 6. press in the new ball joint.
if you don't have a press than you can remove the lower control arm by following steps 1-3 above. then remove the bolt from the front bushing. Remove the stamped steel skid pan from the sub frame. Remove the rear lower control arm bushing mounting bolts.
If you have any questions I'll be happy to answer them.
Hello, Sir is your 1997 Ford Expedition a 4X4? It sounds like the drag line and it's ball joints. There is a bent heavy steel arm at the end of steering box. On the end of this pitman arm is the drag link and the drag link is hook to each front hub with a ball joint on each end and the pitman arm. This way when the steering wheel is turning both wheels in the front will follow each other. If the ball joint are wore out on the drag link this will cause the front wheels to wobble.
Need to get the Ford Exp off the ground where the front wheels are free of a load. Now, just grab one of the front wheels and move it back and forth. There a good possiblity it rattle like marble in a car. Also, check the upper and lower control arms that attached to each front hub. There are hugh ball joint in each control arm, upper and lower on each of the Ford Exp. Two per side four all together. I hope this help you. GB...stewbison
remove the wheel. then take out the lower ball joint bolt.remove the tie rod from the assembly this makes it easy to swing the assembly back and forth. using a ball joint fork insert it between the the ball joint and lower control arm and wack the end on it till the ball joint separates from the control arm. using a pry bar put it thru the control arm so you can pry down on the control arm to release the ball joint then towards the back of the control arm are 2 nuts remove these and remove the cap that they hold towards the front of the control arm is one more nut remove this one and then pull out the control arm replace in reverse order
pull the wheel remove the half shaft nut,take off tie rod end ,take out strut bolts, remove brake caliper,and housing,remove ball joint nuts,seperate control arms from hub bearing housing ,remove hub bearing housing ,then rmove ball joints using a ball joint press(you can rent one at auto zone) ues the press too put the new ones in and put it all back together !!!
these are actually easy to replace on these cars. there are 3 small bolts that hold the ball joint to the control arm. new ball joints are sold with new hardware, so don't worry if it gets damaged when removing. mark the postion of the old ball joint. they can be moved slightly on the control arm to change alignment. the top of the ball joint is clamped into the wheel bearing housing with one large bolt. I use a very large & dull chisel to spread the clamp on the bearing housing if the top of the ball joint is difficult to pull out of the wheel bearing housing.
Remove in this order: wheel, loosen the 4 lower ball joint set bolts, cotter pin and nut from tie rod, tie rod from ball joint bracket, ball joint from lower control arm, 4 lower ball joint set bolts, ball joint from suspension. Install is reverse but don't tighten the 4 lower ball joint set bolts.
torque is as follows: ball joint to control arm- 112 ft-lbs Tie rod nut- 67 ft-lbs lower ball joint set bolts- 83 ft-lbs remember to use a new cotter pin
