#1503 of 1973 Re: 1998 GMC Safari making whine noise sounds like coming from rear end [jmick75]

Sounds like the gears in your van's rear end are going (or starting to go). Might want to get an automotive shop to investigate it further.
If wondering, Safaris/Astros do have under built rear ends. The "most often" hold up during normal driving conditions but tend to blow when towing many hours above 4,000 lbs. Here's a small cut / paste from one consumer report:
It is possible to modify the rear differential to increase durability in intensive usage. To do this, install a bigger oil pan and fill with a high grade oil. 85W140 for standard (non-locking) differentials, and for antislip differentials use 70W90 synthetic oil.
Source file: http://www.apa.ca/template.asp?DocID=23#General%20Motors (look for GENERAL MOTORS Chevrolet Astro, GMC Safari) in the list.
As a suggestion, get your local auto shop to replace the oil in its rear end. Go with the thicker 85W140 (or 70W90) Synthetic oil and hopefully, the whining sound will go away.
Hope this helps...

Well I am back trying to get this van to start. It is a 1995 V^ with 260K . It has new fuel filter and the fuel pump engages when the key is turned. It has a new distributor cap and rotor. It has a new egr valve and the iac has been removed and cleaned. It has a new drive in the starter motor and new solenoid. While seaching for a solution to a rough idle when cold that smooths out when warm the van stopped starting. The rough idle caused me to investigate the coolant temp sensor and it checked out electrically and the amount of coolant is OK. The battery voltage is 12.25v and the positive and negative wires are OK and the ground has been cleaned and tightened. Any help would be appreciated at this point. I looked in the Haynes manual and it also lists the ignitiion swith as a possible culprit??? The van will not turn over and the the starter just makes a EH,Eh,Eh,Eh sound that gets weaker the more I try to start it so I tried to jump it off and no go with that.

Well I am back to trying to get this van to start. All wiring to starter checked out and engine is starting, belts are turning, fan is turning but the "engine won't rotate" as this appears to be the symptom. I tested and replaced ignition coil. Turn on key and hear the fuel pump working but can't test pressure(not running) except when car is off no gas spits out of the relief valve but when the pump is energized(key on) gas spits out so it appears the pump is working just can't tell how well. The engine now makes a puttering ("plop..plop") sound. Someone said I didn't have enough gas fumes so I filled the tank up and the plop got very loud and smoke came out of the engine compartment. AAt this point I don't want to have it towed in...I need to start this van. Any help is appreciated?
#1508 of 1973 94 Asto Van- Hatch Jammed- Left side won't release
Nov 28, 2006 (9:34 am)
I have an automatic release, back hatch on my 94 Chevy Astro Van and I can not open the hatch. The left side seems to be frozen and will not release. I would really appreciate any suggestions on how to fix this problem as the dealer wants $100 just to diagnose and I am hoping this is an easy problem to fix.

I am a 6' 3" large guy and the astro drivers seat (neither manual or power)went far enough back for leg room for me to consider driving a long distance, but 4 bolts to remove the seat and 4 more to remove the track and its a simple matter to relocate the tracks rearward on the seat bolsters about 4 inches, they are bolted together and there is room to relocate them by simply drilling 4 new holes and re installing them. The same could be done to the passengers seat also to accomodate a large rider. have done this to 2 different astro vans and had no problems.

i had the same problem on my 94. you have to get the door open first then at the top of the door where the wires run into the door peel back that cover and one of your wires are probably broke in two. one of mine was broke and the other was ready to brake.
