Whats the rear arm calledon the passenger side that connects the wheel drum to suspension and to the axel it has 3 tapered bolts on it and a bush on each end

That's is really not a good description, but it sounds like a stabilizer bar link. Does this look like the part?

could be rear wheel bearings - they come as a complete assy with brake hub - approx $45 each side - 1 hour per side for replacement. Also replace the rear sway bar links $8 for a set - other than that you could have a bent wheel and or loose rear control arm bolts - remove the rear wheels and check all mounting bolts - I had this problem and my rear end felt like it was shimming when I went around corners - 5 minute fix

It is likely that you have worn rubber bushing in one or more of the suspension control arms, check them all. Also check for loose suspension bolts on all control arms. Have you checked the free play of the wheel?

General Description
The front suspension allows each wheel to compensate for changes in the road surface without affecting the opposite wheel. Each wheel independently connects to the frame with a steering knuckle, ball joint assemblies, and upper and lower control arms.
The control arms specifically allow the steering knuckles to move in a three-dimensional arc. Two tie rods connect to steering arms on the knuckles and an intermediate rod. These operate the front wheels.
The two-wheel drive vehicles have coil chassis springs. These springs are mounted between the spring housings on the frame and the lower control arms. Double, direct acting shock absorbers are inside the coil springs. The coil springs attach to the lower control arms and offer ride control.
The upper part of each shock absorber extends through the upper control arm frame bracket. This bracket has two grommets, two grommet retainers, and a nut.
A spring stabilizer shaft controls the side roll of the front suspension. This shaft is mounted in rubber bushings that are held by brackets to the frame side rails. The ends of the stabilizer shaft connect to the lower control arms with link bolts. Rubber grommets isolate these link bolts. Rubber bushings attach the upper control arm to a cross shaft. Frame brackets bolt the cross shaft.
A ball joint assembly is riveted to the outer end of the upper control arm. A rubber spring in the control arm assures that the ball seats properly in the socket. A castellated nut and a cotter pin join the steering knuckle to the upper ball joint.
The inner ends of the lower control arm have pressed-in bushings. The bolts pass through the bushings and join the arm to the frame. The lower ball joint assembly is a press fit in the lower control arm and attaches to the steering knuckle with a castellated nut and a cotter pin.
Ball socket assemblies have rubber grease seals. These seals prevent entry of moisture and dirt and damage to the bearing surfaces.
Four-wheel drive models have a front suspension that consists of the control arms, a stabilizer bar, a shock absorber, and right and left torsion bars. The torsion bars replace the conventional coil springs. The lower control arm attaches to the front end of the torsion bar. The rear end of the torsion bar mounts on an adjustable arm at the crossmember. This arm adjustment controls the vehicle trim height.
Two-wheel drive vehicles have tapered roller sheel bearings. These bearings are adjustible and need lubrication.
Four-wheel drive models and RWD Utilities have sealed front-wheel bearings. These bearings are pre-adjusted and need no lubrication.
Heat treatment may create darkened areas on the bearing assembly. This discoloration does not signal a need for replacement.
Hope this helps?

The following describes the entire rear suspension of which if any parts are worn can cause a noise:

Removal & Installation

1. Before servicing the vehicle, refer to the Precautions Section.
2. Remove the rear wheels.
3. Using a suitable jack, support the rear lower arm.
4. Remove or disconnect the following:
   
   Rear wheels Stabilizer bar link Rear lower arm Jack Lower arm from subframe Spring Isolator
   
   

   Fig. Rear suspension assembly-S-Type
   
   

To install:

1. Install or connect the following:
   
   Isolator Spring Lower arm: Tighten bolt to 85 ft. lbs. (115 Nm). Stabilizer bar link: Tighten bolt to 26 ft. lbs. (35 Nm). Rear wheels
   
2. Check rear wheel alignment and adjust as necessary.

For all except the X-Type, the rear coil spring is serviced with the strut assembly.

LOWER CONTROL ARM

REMOVAL
1) Raise and support vehicle. 3) Remove the steering knuckle.
Remove the bolts fastening the power steering cooler to the front suspension cradle crossmember reinforcement (Fig. 21). 5) Remove the lower control arm rear bushing retainer bolts located on each side of each lower control arm rear bushing. NOTE: The bolts fastening the cradle crossmember reinforcement are of three different thread sizes. Note the location of the various sizes.

6) Remove the bolts attaching the cradle crossmember reinforcement to the front suspension cradle crossmember (Fig. 22). Remove the 2 bolts fastening the reinforcement and rear of cradle crossmember to the body of the vehicle. Remove the reinforcement. 7) Remove the pivot bolt attaching the front bushing of the lower control arm to the front suspension cradle crossmember. 8) Remove the lower control arm.

Removal

1. Raise the rear of the vehicle, and support it with safety stands in the proper locations.
2. Remove the rear wheel.
   1. Position a floor jack at the connecting point of the trailing arm (A) and the knuckle (B). Raise the floor jack until the suspension begins to compress.
   2. Remove the flange bolt (C) from the bottom of the damper. Discard the bolt.
   3. Remove the trunk side trim panel.
   4. Remove the self-locking nut (A) while holding the damper shaft (B) with a hex wrench (C).
      1. Compress the damper unit (A) by hand, and remove it from the vehicle.
      Inspection
      
      1. Push on the damper as shown.
      2. Compress the damper assembly by hand, and check for smooth operation through a full stroke, both compression and extension. The damper should extend smoothly and constantly when compression is released. If it does not, the gas is leaking and the damper should be replaced.
      3. Check for oil leaks, abnormal noises, or binding during these tests.
      Installation
      Install the damper mounting bushing (A) onto the damper unit. Position the damper assembly (B) between the body and trailing arm. Be careful not to damage the body
      
      
      1. Position a jack under the trailing arm to support the suspension, then install a new damper mounting bolt (A).
      2. Loosely tighten the damper mounting bolt.
      3. Raise the rear suspension with the jack until the vehicle just lifts off the safety stands, then tighten the damper mounting bolt to the specified torque value.
      4. Install the damper mounting bushing (A), the damper mounting washer (B), and a new self-locking nut (C) on the damper shaft.
      5. Tighten the self-locking nut to the specified torque value while holding the damper shaft (A) with a hex wrench (B).
      6. Remove the trunk side trim panel.
      7. Install the rear wheel. NOTE: Before installing the wheel, clean the mating surface of the brake disc or brake drum and the inside of the wheel.
      8. Check the wheel alignment, and adjust it if necessary

Does it have what's called trailing arms on the rear suspension ---inspect the main BIG bushings
that connect it --common problem on alot of vehicle
some are DIY some are not depending on basic hand tools skills and proper support
jack stands ---plural on purpose --safe dry location
some are easy bolt in and replace some are press in and out --- a machine shop or "Friend" may Macguyver it for you and poof fixed ---ahhh it's free advice take what you can---

i don't think you have to do any repairs from the top end. I will list most fromFord shop manual. Please rate as Fixya if this answers your questions. Please report back. Good luck.
