Do I need to align the tires after installing new struts on both front and rear?

front

1. Install or connect the following:
   • Strut assembly
   • Fork to the strut and torque the bolts to 59 ft. lbs. (80 Nm)
   • Fork to the lower arm and torque the bolt to 88 ft. lbs. (120 Nm)
   • Upper strut mounting nuts and torque to 36 ft. lbs. (50 Nm)
   • Brake hose bracket
   • Front wheel
2. Check and/or adjust the wheel alignment.

--------------------rear------------

To install:

1. Install or connect the following:
   • Strut assembly and mounting bracket and torque the bolt to 36 ft. lbs. (50 Nm)
   • Upper arm and rear carrier bolt and torque the bolt to 88 ft. lbs. (120 Nm)
   • Lower mounting bolt
   • Rear wheel

It sound like the Camber is off in the rear. Did you have an alignment done after the new struts wear installed?

Wearing on the inside can be caused by an excessive camber angle or excessive toe out, or both. Either of these can be caused by worn or damaged suspension parts. Camber affects Caster, and Camber and Caster affect Toe. Toe affects the Thrust Angle. (These are the major suspension angles involved in wheel alignment) The "dishing" or "cupping" is caused by what is sometimes called "wheel-hop" this can be caused by worn-out struts or shocks and can also be caused by tires that are seriously out of balance.

The recommended "Fix" would be to inspect the ENTIRE suspension system to check for loose and/or worn and/or damaged parts. Replace any of these parts as necessary. Then replace and balance the tires and head straight over to the alignment shop to have all of your suspension angles set to manufacturer's specifications. (Most tire stores also have an alignment machine)

get a front end alignment done as soon as possible

Yes loosening the top strut/bracket is needed to adjust the alignment, the rear should be fine unless there is damage to rear suspension compontents that need replaced, however for that vehicle just the front.

REMOVE**** FRONT SHOCKS, FIRST OF ALL.SUPPORT THE LOWER CONTROL ARM WITH A JACK,REMOVE FRONT WHEEL, REMOVE BRAKE HOSE AND ABS SENSOR HARNESS TO THE STRUT BOLTS OR CLIPS,REMOVE ACTUATOR FROM TOP OF THE STRUT,IF EQUIPPED WITH AUTOMATIC ADJUSTING SUSPENSION. PAINT ALIGNMENT MARKS ON THE UPPER STRUT MOUNTING BLOCK AND STRUT TOWER AND ON THE LOWER STRUT MOUNT TO STEERING KNUCKLE SO THAT CAN BE REINSTALLED IN THE SAME POSITION. REMOVE UPPER STRUT MOUNTING NUTS, REMOVE THE STRUT TO KNUCKLE BOLTS,REMOVE STRUT ASSEMBLY.TO INSTALL ***** INSTALL STRUT INTO THE STRUT TOWER ALIGNING THE PAINT MARKS MADE DURING REMOVAL.INSTALL UPPER MOUNTING NUTS AND TIGHTEN TO 34 - 46 FT LBS. INSTALL STRUT TO KNUCKLE BOLTS TIGHTEN TO 55 - 61 FT LBS. INSTALL ACTUATOR AND ENGAGE THE ELECTRICAL CONNECTOR IF EQUIPPED WITH AAS. INSTALL BRAKE HOSE AND ABS SENSOR HARNESS CLIPS OR BOLTS.INSTALL WHEEL AND CHECK ADJUST THE FRONT END ALIGNMENT. TO ( REPLACE REAR SHOCKS ) REMOVE REAR WHEELS, REMOVE REAR PACKAGE TRIM. REMOVE SPEED SENSOR HARNESS, REMOVE TOP STRUT NUTS,THE SUSPENSION WILL DROP WHEN THE WEIGHT LIFTS OFF THE WHEELS. REMOVE BOTTOM STRUT BOLTS.REMOVE STRUT ASSEMBLY.TO INSTALL ***** INSTALL STRUT ASSEMBLY, INSTALL BOTTOM STRUT MOUNT BOLTS AND TIGHTEN TO 55 - 61 FT LBS.INSTALL UPPER MOUNTING NUTS AND TIGHTEN TO 33 - 46 FT LBS. INSTALL SPEED SENSOR HARNESS.INSTALL REAR PACKAGE TRIM. INSTALL REAR WHEELS.

You will need an alignment. The strut is slotted to allow camber adjustment.If the tire is leaning in then the camber is excessively negative.

check the ball joints and wheel bearings front and rear

This sounds like either a wheel bearing a bent axle or an alignment problem, the alignment shop will check all these before they do anthing with the alignment.

first of all firestone are rip off artist. you got suckered. next there are struts on the back and yes you should align them however it has more to do with how the tire wears than a steering issue. with only 12,000 miles I seriously doubt there would have been a problem. my solution would have been if one of the front tires was bad i would have replaced it then took the 2 back tires and put them on front and the new tire and other front tire on the back and no alignment would have been needed unless your girlfriend would have complained about it tracking one way or the other. feel free to click on my user tab anytime you need help.... please rate this.........thanks
