The power steering gear broke off of the frame in my 1989 gmc suburban 5.7L, 350 v8. How can This be repaired? cant drive truck, turning left just causes the steering gear to bend in engine compartment and leak fluid. one bolt was missing and the other one broke through the frame. Help!

No relay.
Headlights are powered directly from the headlight switch.

Hi.

Below you get all the parts breakdown for GMC Sierra 1500, including steering column assembly:

1500 SIERRA

Here diagrams for all 1989 GMC trucks.

If you need to take apart the steering column you will also need wiring. below the color codes and wiring tips:

set the front wheels in straight ahead position by driving vechicle a short distance on a flat surface. raise and support the vechicle safely on jack stands.place a drain pan below the steering gear. disconnect negative battery cable.disconnect fluid lines.cap the openings.mark the relationship of the pitman arm to the pitman shaft.remove pitman shaft nut and then remove the pitman arm from the pitman shaft using puller J - 6632. remove the steering gear to frame bolts and remove the gear assembly. TO INSTALL align the flat of the flexible coupling with the flat on the shaft push the coupling onto the shaft until the wormshaft bottoms against the end of the shaft.install the pinch bolt. make sure the bolt passes through the shaft undercut. tighten the pinch bolt to 75 ft lbs. place the steering gear into position guiding the coupling bolts into the proper holes in the shaft flange. install the steering gear to frame bolts and torque to 66 ft lbs.install the coupling flange nuts and washers. make sure the coupling alignment pins are centered in the flange slots. tighten the nuts to 20 ft lbs. maintain a coupling to flang dimension of 0.250 - 0.375 inches. install the pitman arm.install the hoses. you are done except bleeding power steering system. BLEEDING POWER STEERING. fill the the power steering pump reservoir to the proper level and let the fluid remain undisturbed for at least 2 minutes. start the engine and run it for only about 2 seconds.add fluid as necessary. keep doing this procedure until fluid level stop dropping. then raise the front of vechicle so the front wheels are off the ground.set the parking brake and block both rear wheels front and rear. manual transmission should be in neutral. automatic transmission should be in park. start the engine and run it at approximately 1500 rpm. turn the wheels off the ground to the right and left lightly, contacting the stops.add fluid as necessary. lower the vechicle and turn the wheels right and left on the ground.check the level and refill as necessary. if the fluid is extremely foamy, let the vechicle stand for a few minutes.with the engine off and repeat the procedure. if fluid looks foamy. once all done.dont drive vechicle on highway until normal steering is obtain.

there are no lines inside the frame , you may have a leaking line but not inside the frame, it may look like its inside but not, clean the area good and then watch for a leak as someone turns the steering wheel, at the gear box you will see two lines a preasure and return line, the preasure goes from gearbox to pump and the return goes from gear to pump also, some trucks may have a cooler, if this is the case the only diffrence is the return will go from gearbox to cooler to pump, this is all the lines none are in the frame, good luck.

Not sure but the flasher unit is separate from turn signals and most vehicles the turn flasher unit is not far from the steering wheel post up under the dash.

would imagine the internal speedo gears are skipping when cold. They are located in the transmission where the cable goes into. It is easily removed to inspect

thats a real simple unit, either the pumps input shaft sheared or the drive hub that that shaft engages into the torq converters spot welds broke. happens on rebuilt torq converters from time to time, either way its gota get pulled. a 2wd is very easy to remove and cheap to repair good luck!

The high pressure and low pressure hoses are different sizes at the gear box. And the low pressure /return hose is usually rubber with a clamp at the back off the pump.

4X4? you have to disconnect steering shaft from steering column lock steering wheel with seat belt first, then remove power steering lines and then the 3 bolts that hold the gear box to frame rail, any problems write back please give feed back

rack and pinion sounds like its going bad
