#1862 of 1973 Re: can I lift my 99' Astro? [dlm1954]
Mar 05, 2009 (10:51 pm)
Early 95 model and older of Astro/Safari vans had single fiberglass leaf system. Mid 1995 and newer years (like my 2001 van), their factory build was 3 leaf steel spring system. For early 1995 and older leaf spring conversion kits, surf: http://www.stengelbros.com/SteelReplacementSprings.htm
For 1999 AWD, one can install +1 leaf (mid length leaf) in the rear. This firms up the rear's suspension but it also lifts the van's rear 1.5". Because the rear goes up, the front slightly goes down. To raise the front by .5" (for better looking & balanced stance), one can adjust the front torsion bars. And to reduce factory mush "depth" in the front, one can also install Timbrens in the front. Wish I had spare dollars to install Timbrens in the front of my 2001 AWD's front. Perhaps one day...
For 1999 RWD, one can install +1 leaf (mide length leaf) in the rear. This firms up the rear's suspension but is also lifts the van's rear 1.5" Because the rear goes up, the front goes down. To reduce factory mush "depth" in the front, one can install Timbren SES units in the front. Or, install HD coil springs in the front - for better looking & balanced stance.
For more details about Timbren units, surf middle page of: http://www.timbren.com/timbren-application-guides/chev-gmc.htm
Some folks pick Air Bag upgrades, some folks pick Timbren upgrades, some folks pick +1 leaf upgrades and some folks pick a combination of each solution. Each product has its own pros/cons/cost and "ease of use".
Hope this helps as well...

I have an '04 Astro with a 101K miles 2WD. When I pull to a stop at an intersection or stoplight, sometimes the tranny seems to stick in 3rd and when I start going again I can feel it downshift into 1st. It seems odd that it would do that. It has happened a couple of times before, although not frequently. What could be causing this? Fluid level is normal. No other indicators that I can think of. It shifts fairly normally, although a little rough sometimes, but I think that is typical of this transmission (4L60E).

Ive got about 176k miles on my astro 2wd and have been adding supplements to the fluid since 75k. Fluid my look fine, but its effectiveness my be little to none.
Throw some tranny slip-fix in there and see what happens. I personally use Lucas transmission fix to top it off regularly.

#1866 of 1973 rear door issues
Mar 28, 2009 (1:48 am)
I got a 99 GMC Safari. Since about one week the rear upper door want open. It seems like some kind of electrical problem ´cause there is no sound after pressing the door button. There is some kind of lock mechanism inside which normally have to move both strings inside to unlock the door. the mechanism is working fine, I connect 9V battery and the mechanism moved. Is just problem with the button. I also sprayed WD40 an conntact cleaner inside. Nothing works. I checked already all fuses and relays-all fine. Maybe someone had the same issue. PLZ help.
#1867 of 1973 2000 GMC Safari has spark dead end at the distributer cap but
Apr 14, 2009 (9:47 am)
I have a 200 GMC Safari 140K miles on it. We had one snow storm drop 13 inches of snow on us in Indy. The van did great in it but every since, when ever it rains or is wet out It wont run. I've changed the fuel filter, dis. cap, rotor, wires, plugs, O2 sensors, and cat. converter when the peoblem first started and it was spitting out the P0420 code one week after that big snow storm melted. I had the fuel pump changed for the 3rd time while it was still under warrenty about 1 month before the storm. Now it's stranded out in front of my house it has spark all the way to the dis cap but nothing from there. I tested the Cam Poss. sensor last night by backprobing the connector with the connector attached to the sensor and I got a pulse reading so I guess that sensor is ok. This is supposed to be the last wet day untill this weekend. So it might run tommoro

Sounds like you have spent a lot of time and money. Have you put any "dry gas" in it? Moisture / dampness could be the problem. Good luck.

I would check for a bent exhaust pipe, my wife caught my tail pipe backing out of my driveway in all that snow and tore it off. If it had bent it,it would not have run right or at all. If you have fire intermittently at the distributor it also could be a bad wire on the coil that's not getting a good connection. I just replaced one on my motor home last year from sitting, the wire connectors had a coating of corrosion which attracts moisture. But that code is usually associated with an exhaust especially converter problem, I would check for bent pipes first; a bent pipe would play havoc with the O2 sensor I would think and I've seen it before. Their's also a main wiring bulkhead that plugs into the fuse box through the firewall that sits behind the battery the main ignition wire pulls so much power it will melt in that bulkhead and loose connection in damp weather, I've had a lot of problems with that on my ASTRO, it should have been hard wired but about every vehicle made is the same way, the wiring bulkhead plugs into the firewall into the back of the fuse box.
GOOD LUCK DLM1

I had this same problem. I ended up changing the coil and the ignition module and it fixed the problem.
As soon as it was damp outside if wouldn't start. I hope this will fix yours.
#1871 of 1973 94 Safari, Idle problem
May 11, 2009 (4:18 am)
Hi.I`m the 94 GMC Safari owner.
For a last couple of month i`m experiencing a rough idle problem.When engine starts RPM goes very high and when i`m shifting from P car jumps forward like crazy.Since I`m from Europe it almost impossible to find a good mechanic for an american car here.I changed an Idle Air Control Valve since the old one was dead but it didn`t help much.Now when engine starts it runs smoother but when i shift to D - same story and when i shift back to P the RPM goes even higher than before.
Can anyone help me?Thank you.
