I have been reading threads and trying to figure out where to start. I am narrowing it down to the ABS system but I am unsure. The difficulty is live in Nevada and the burb is in Alaska with limited resources for help. The suburban sits most of the year and has only seen 18000 miles in the last 10 years. It currently has 218000 miles.
1993 K2500 heavy with the 5.7 and hydro boost. I don't recall but it was the heaviest axles and brakes available. Government rig
Last month while driving to the cabin on pavement at 60 mph a vibration started. It was very obvious and the kind that shook the mirrors but not yet violent. I pulled over to look at tires etc and when I took off again it was gone. It was driving smooth underway and while no braking. About 30 minutes later it came back so I stepped on the brakes fairly firmly and the car shook fairly violently. I brought it to a complete stop and took off again a minor vibration remained then cleared.
In town while putting the boat in the water and backing down the ramp the ABS and brake light came on and has stayed on. Ever since I had the car when I hit 10 mph for the first time a noise like a spring unwinding goes off only once. I allows assumed it was the ABS. It has stopped.
On the way back to Ketchikan yesterday, in the dark of course, the heavy shakes came back. It is the whole car and not in the brake pedal or steering wheel. What seems to work is if I bring it to a complete stop and back up quickly and lock the brakes I can continue on for a while before it returns. With limited ability to test it seems like if I do not touch the brakes I am good for a while and if I come to a complete stop when I do its fine. I am thinking when I lightly apply the brakes in a curve and continue on the vibration returns until I do the complete stop and back up again. Again, when this begins and I step on the brakes to come to a complete stop it is quite dramatic.
Prior to the last drive to the airport I was leaning towards something sticking in the rear drums so I put parts I had on hand in the car to repair nest trip. I was going to replace the drums, pads and springs. When this occurred last month I thought sticking caliper pins so I pilled them, cleaned them up and lubricated the pins with high temp brake grease.
There are mechanics in Ketchikan but not all of them are fully versed in all cars and I have no idea if anyone has the ABS related electronics to properly bleed the ABS system. I am at a loss of where to begin. I am still going to put the rear drums, spring and pads on when I get back in November but I no longer am convinced its rusted parts and springs in the rear drums.
Thoughts on where to start?
Thanks for any help. I will need to collect parts here in Nevada and attack it in the cold November rain when I get back.
