I have a 1999 ford ranger with a little over 75000 miles on it. Just recently the truck starts bouncing when i'm driving and it's very random. Comes and goes. It's the front end and it goes up and down as if the tires were oval. Also, very random too, but more consistent, when I brake the steering wheel pulls to the right. And sometimes a metal burning smell coming from the front wheel wells area. What's the matter?

Shocks for the bouncing, and inspect the brakes, you may need calipers and pads, possibly a rotor if it's metal to metal. Check soon! Saftey issue!

I have the same issues in my 95 4x4. The brakes are good, the shocks have not been replaced in about 24k. Not that many miles but it is the intermittency that makes me wonder.

For the 4X4 version and any torsion bar suspension types, read this TSB, may be part or all of the problem.
REVISED PROCEDURE FOR ADJUSTING ALIGNMENT ON ALL SUSPENSIONS - NEW RIGHT HAND UPPER CONTROL ARM DESIGN FOR TORSION BAR FRONT SUSPENSIONS TECHNICAL SERVICE BULLETIN Reference Number(s): 04-24-19, Date of Issue: December 13, 2004 Related Ref Number(s): 04-24-19 ARTICLE BEGINNING DESCRIPTION REVISED PROCEDURE FOR ADJUSTING ALIGNMENT ON ALL SUSPENSIONS - NEW RIGHT HAND UPPER CONTROL ARM DESIGN FOR TORSION BAR FRONT SUSPENSIONS ISSUE The cam bolt and nut kit that was used for adjusting caster and camber on all torsion bar and coil spring front suspensions has been discontinued. If the caster and camber settings need to be adjusted, a washer must now be installed. The right hand upper control arm design changed from a two piece design to a single piece design during the 2003 model year. The single piece design is now the only version of the upper control arm available for service of prior model year Rangers. ACTION Use the following Camber And Caster Adjustment procedure when either camber or caster need to be adjusted on any suspension, or if only a caster split adjustment is needed on a vehicle equipped with single piece upper control arm. Use the following Caster Split Adjustment - Two Piece Right Hand Upper Control Arm procedure if only a caster split adjustment is needed on a vehicle equipped with a two piece upper control arm. SERVICE PROCEDURE CAMBER AND CASTER ADJUSTMENT FORD: 1998-2001 Explorer; 1998-2003 Ranger; 2000-2003 Explorer Sport; 2001-2003 Explorer Sport Trac NOTE: THE UPPER CONTROL ARM-TO-FRAME MOUNTING BOLTS HAVE SET SHIMS THAT MUST BE REPLACED WITH WASHERS TO ALLOW FOR ADJUSTMENT OF THE ARM IN THE FRAME SLOT. THE VEHICLE SHOULD BE SUPPORTED BY THE LOWER CONTROL ARM TO EASE MOVEMENT OF THE UPPER ARM IN THE SLOT.
1. Remove and discard the upper control arm-to-frame nuts and shims ( Fig. 1 ). Fig. 1: Upper Control Arm-To-Frame Nut 2. Install new washers (W705040-S900) and nuts (N805480-S427). Tighten the nuts so there is tension, but the upper control arm can be moved for the alignment adjustment. 3. To adjust caster and camber refer to the following chart. Adjustments that require moving the front and rear of the upper control arm should be made equally. CASTER/CAMBER ADJUSTMENT 4. Torque the upper control arm-to-frame nuts to 98 lb-ft (133 N.M). 5. Check and if necessary adjust the front toe. Refer to the appropriate Workshop Manual for information. CASTER SPLIT ADJUSTMENT - TWO PIECE RIGHT HAND UPPER CONTROL ARM 1. To decrease the right hand caster, loosen the ball joint adjustment nuts ( Fig. 2 ) and move the ball joint forward. Fig. 2: Ball Joint Adjustment Nuts 2. To increase the right hand caster, loosen the ball joint adjustment nuts and move the ball joint rearward. 3. Torque the ball joint adjustment nuts to 129 lb-ft (175 N.M). 4. Check and if necessary adjust the front toe. Refer to the appropriate Workshop Manual for information. PARTS INFORMATION PARTS INFORMATION

Thanks for the reply. Do you think that will work for the 1995 Ranger? They mention 98+ Explorers and 98+ Rangers.

Thanks again!
