The noise happens when turning, parking and backing up. Seems noise is around torsion bars.
Dealer is quoting possibly 3gs
The oil level is always full but the oil pressure gauge is always fluctuating between 20 and 40. None of the dash lights are on. So I don't know what to do. The tapping sounds a bomb ticking.

During the winter I had heater on low and all of a sudden it turned up to high by itself. I couldn't turn it off for like a week and a half and then it stopped working. I am wondering what the problem might be, I checked the fuses and they were all good.
We don't know what IT could be
I have changed the fuel pump, fuel filter, the fuel relay switch, which gets really hot for some reason, changed the EGR valve. I took it into a mechanic and they thought it was a vacuum leak, and they said they checked it all and thought they found one. They called me and said it hasn't stalled and think its fine. Went and picked it up and I wasn't even a block away and it stalled as I was driving, had to pull over(keep in mind still has power, pulled over put in park then started it back up and it started. Drove it home no issues, drove it the next day and same issues..... Tried troubleshooting it myself again, looked at the vacuum diagram and it showed they had the hoses switch for the one going to the fuel tank. So I switched them, drove it for two days and it was fine. Then today it was back to same issues but much worse, just be driving along and rpm drop to 0 then it stalls out and have to pull over, sometimes it will start right back up, but today it just wasn't happening.... Any idea's, thoughts, would be greatly helpful, just don't have the money to take it into a mechanic, pretty good with vehicles and have worked on a few, but this one has me so confused.....
My truck won't take gas. Replaced canister purge valve, solenoid under hood near intake & fuel cap, finally took to shop & they replaced fuel vapor canister & blew out all the lines. Still NOTHING after all of that.
The fuel tank pressure sensor above the gas tank has not been replaced as of yet.
Any input? What good is his "New state of the art diagnostic station"???

Left work truck was fine stopped at store came out started it up and I lost powersteering and brakes are hard. Thats when i seen the return hose to the gear box was off. I replaced the power steering pump and the Hyrdro-Boost. Tried to bleed the hydro-boost but nothing comes from the return hose. I believe there is high pressure on both sides of gear box not allowing flow or there is blockage in line or a seal has failed somwhere. Please help.
I turn the selector to either 4 auto, 4 hi, or 4 lo. The indicator light will continually flash and I hear a click like the transfer case is shifting but will not actually engage. I have tried in park, in neutral, slowly rolling and even at moderate speed (30mph).
car is off. Is there some button or something that will turn them off when the car is not running? Of course the battery goes dead. Not sure of the year, can't find any papers or manual for this car in the glove department.
I had my oil changed and now the engine knocks?? The oil level is good, but the noise just started. Could it be the lifter? And what will happen to the engine if I drive like this?
