Front Suspension
1 Upper Ball Joint (driver and passenger side)
The upper ball joint is the top pivot of the steering knuckle. It is pressed into the upper ear of the axle C and lets the knuckle turn.
Signs of wear: Wandering, a clunk over bumps, uneven tire wear, or play when the tire is rocked top to bottom with the front lifted.
Tip: Offset upper joints are sold in degree steps to correct camber and caster on leveled trucks. Replace both sides and get an alignment.
See all Front Upper Ball Joint parts for the 1998 Dodge Ram 3500 4WD
2 Lower Ball Joint (driver and passenger side)
The lower ball joint is pressed into the lower ear of the axle C and carries the bottom of the knuckle.
Signs of wear: Play at the bottom of the tire, clunks when turning, or a torn boot.
Tip: Lower joints usually wear first. Do both sides together.
See all Front Lower Ball Joint parts for the 1998 Dodge Ram 3500 4WD
3 Upper Control Arm (driver and passenger side)
Each upper control arm runs back from a bracket on top of the axle tube to a bracket on the frame. With the lower arm it holds the axle in place front to back and sets the caster.

Questions about the 1998 Dodge Ram 3500 4WD suspension
Which steering parts fit my 1998 Ram 3500 4x4?
The 1998 and 1999 Ram 3500 4x4 uses the heavy duty linkage drawn here: the long DS1456 tie rod with the DS1459 drag link, a 1-1/8 in sleeve and the ES3496 end at the driver knuckle, and the ES3497 end with its sleeve at the pitman arm. 1994 to 1997 trucks use different rods.
What causes the front end shake on a second generation Ram 3500 4x4?
A shake after a bump usually comes from worn steering or track bar parts: the tie rod and drag link ends, the track bar ball stud at the frame, the track bar bushing at the axle, and the ball joints. A new steering damper can hide it for a while, but check those parts first.
Do the parts differ between a single and a dual rear wheel Ram 3500?
Our catalog lists one set of rear shocks, brake shoes, shackles and spring bushings for every 1998 and 1999 Ram 3500 4x4, with no single or dual wheel note. The diagram shows a dually; the rear axle and wheels differ on single rear wheel trucks.
Do I need an alignment after replacing front end parts?
Yes. Replacing tie rods, the drag link, ball joints or control arms changes the alignment. Toe is set at the large tie rod sleeve and the steering wheel is centred at the drag link sleeve.
Which years share this suspension?
The 1998 and 1999 Ram 3500 4WD share this front axle, steering and brakes. 1994 to 1997 trucks use other steering rods, pads and a different steering damper, and 2000 and later trucks changed the front end, so order by year.
