  Q: How to replace the underhood fuse box on Chevrolet Suburban 1500?

  A: The first step when replacing an underhood electrical center or junction block requires disconnecting the negative Battery Cable and taking out the left fender upper brace. You must raise the electrical center brace cover from its base to expose the tabs and after that remove all fuses and relays. A grip of the tab will unlock the electrical center from its stud location at while you remove each connector through its bolt . All electrical connectors must be removed from the block while using tabs to raise the electrical center upward from the housing. The replacement of the engine electrical center bracket requires removing the 4 retaining bolts which allows extraction of the assembly from its fender position. The engine electrical center bracket assembly needs to be secured to the front fender by using 4 retaining bolts which must be tightened to 9 n.m (80 lb in). Secure the electrical center block stubs into their designated slots before the tabs catch them securely. Subsequently, connect wire connectors to the electrical center block bottom half and fasten them using bolts which need tightening to 9 n.m (80 lb in). The electrical center block must be placed correctly so that its tabs secure the block in position. The installation order requires officials to first place the lower cover section before locating fuses and relays according to the information chart to finish with the cover application. The fender upper brace installation requires you to attach it using 4 bolts which must be tightened to 25 n.m (18 lb ft).

  Q: How to replace the catalytic converter on Chevrolet Suburban 1500?

  A: After supporting the vehicle and transmission with proper equipment, begin the Catalytic Converter replacement process. Start by removing the transmission mount nuts to transmission support then lift the transmission away from the support before you extract the transmission support crossmember bolts and nuts leading to the crossmember's removal. The engine harness along with its oxygen sensor pigtail requires clip removal. After that disconnect the connector position assurance (CPA) retainers and oxygen sensor electrical connectors. Unclip oxygen sensor connectors both from the hose clip and transmission crossmember followed by a second disconnect of the oxygen sensor cpa retainers and electrical connectors (1, 2). Follow this sequence to remove the Catalytic Converter - first unfasten the left and right exhaust manifold pipe nuts and next disconnect the exhaust muffler nuts then remove the Catalytic Converter. You should apply gm p/n 12377953 anti-seize compound with equivalent material to old oxygen sensor threads before installation. Torque the sensors to 42 nm (31 ft. Lbs.). Drive the right and left exhaust manifold pipe nuts halfway by hand before torqueing them to 50 nm (39 ft. Lbs.). Next, install the new Catalytic Converter alongside new exhaust manifold pipe seals mounted on the exhaust manifolds. Use 40 nm (30 ft. Lbs.) torque when tightening all exhaust muffler nuts. The oxygen sensor electrical connectors (1, 2) and cpa retainers need installation before you secure the oxygen sensor electrical connectors to the hose clip and transmission crossmember. First tighten the transmission support crossmember bolts and nuts to 95 nm (70 ft. Lbs.) then reinstall the crossmember before installing the engine harness and oxygen sensor pigtail in their clips. Finally reattach the cpa retainers and oxygen sensor electrical connectors. Place the transmission mount on the support then bolt it to the transmission support nuts while torquing them to 40 nm (30 ft. Lbs.). Lower the vehicle while removing the transmission jack.

  Q: How to replace the emblem/nameplate on the end gate on Chevrolet Suburban 1500?

  A: Obtaining tools to replace the emblem/nameplate at the end gate (excluding RPO B4U) begins with building the following list of tools: Use Heat Gun J 25070 together with 3M(TM) P/N 07501 Molding Adhesive Remover Disk from 3M(TM) Scotch Brite. Heat Gun (J 25070) and 3M(TM) Scotch Brite Molding Adhesive Remover Disk (3M(TM) P/N 07501). Use protective tape first then position it around the emblem area before beginning. Use a Heat Gun (J 25070) to heat the emblem/nameplate from 152 mm away (6.0 inches) for about 30 seconds in circular motions. Use a plastic flat tool for careful endgate surface emblem/nameplate removal. Clean both the endgate panel surface and the emblem/nameplate rear surface completely free of adhesive by using a 3M(TM) P/N 07501 Molding Adhesive Remover Disk in combination with varnish makers and painters (VMP) naptha. When no marks indicate the emblem/nameplate position, install tape. Use the Heat Gun (J 25070) to warm the endgate surface to 21°C (70°F) and above while maintaining contact between both the emblem/nameplate and adhesive backing. Press the front side of the emblem/nameplate onto the endgate panel as you gradually remove its backing. Use hand pressure to press-roll the emblem/nameplate until it sticks properly then check bonding before removing the tape from the endgate emblem area.

  Q: What tools are required to replace the front inner axle wheel seal or bearing on Chevrolet Suburban 1500?

  A: The replacement of front drive axle inner axle seal or bearing requires the following tools: housing drive gear seal installer (J22833) for 9.25 inch axle along with j2619-01 slide hammer along with bushing and bearing remover tools j29369-1, j29369-2 for 2-3 inch use, output shaft seal installer (J36600) for 8.25 inch axle and axle tube bearing installer (J36609). A technician should first lift the vehicle before draining the differential carrier assembly. To work on right side seal or bearing you must first separate the differential carrier case from its inner Axle Shaft housing assembly before disassembling Clutch Fork assembly components from inner Axle Shaft housing. Mount the inner Axle Shaft housing into a vise while securing it only on the mounting flange. First attach the j29369-1 or j29369-2 behind the inner Axle Shaft seal or bearing according to requirements before using the j2619-01 to extract either the seal or bearing. You must remove the differential carrier assembly and fix it in a vise before extracting the inner Axle Shaft using a hammer with brass drift. Finally install the j29369-1 or j29369-2 behind the inner Axle Shaft seal or bearing while using the j2619-01 to detach them. Put the bearing installation in place by fixing the inner Axle Shaft house in a vise then installing it with a j36609 and j8092. The installation of the inner Axle Shaft seal requires the j36600 or j22833. Insert the inner Axle Shaft with gentle mallet taps using a soft-faced mallet before reattaching all differential carrier case components comprising the Clutch Fork along with the inner Axle Shaft housing assembly. The same installation process with tools should be repeated to install bearing and seal on the left side. Toward completion you must add correct fluid into the differential carrier assembly before lowering the vehicle.
