2003 Buick LeSabre Shock Absorber Parts Questions & Experts Answers

• Q: How to service the front shock absorber assembly on 2003 Buick LeSabre?

  A: The first step to service front suspension struts should involve gentle coil spring handling because improper treatment of their coating produces premature failure. The service begins by removing two retaining bolts from the strut mounts after lifting and supporting the vehicle before disconnecting the tire and wheel. Connectors for the abs front wheel speed sensor harness should be separated from each other while also taking out the speed sensor bracket that attaches to the strut if present. You must keep the knuckle secured after removing the bolts between strut and knuckle because this protects the Ball Joint together with wheel drive shaft from damage. The process starts with removing the Brake Line bracket from the left-side strut before removing the one nut and three strut-to-knuckle bolts to extract the strut outside of the vehicle. Lower the vehicle to install the strut by placing it accurately into position while using required fasteners according to specified locations. The service procedure documents all fasteners which need to be replaced alongside those requiring thread locking compound or sealant. Adhering to fastener and their joint surfaces requires avoiding any application of paints, lubricants and corrosion inhibitors because these agents negatively modify torque and clamping force. Proper follow-up of sequence and specifications for tightening will avoid damage to the system. Mount the strut to its body retaining bolts while applying torque of 47 nm (35 lb ft). After the second vehicle lift reposition each of the three strut-to-steering knuckle bolts and nut before torquing them to 147 nm (108 lb ft). After attaching the Brake Line and retaining bolt to the strut assembly you should install the speed sensor bracket if necessary along with its retaining bolt. Secure all retaining elements to 17 nm (13 lb ft). The abs front wheel speed sensor harness connector can be reinstalled after which you will install the tire assembly, lower the vehicle, then perform a front wheel alignment.
