Every since getting the 89 Blazer back in December, it has had a BANGing noise in the rear near the tailgate whenever going over rough road, pot holes or any real bumpy stuff.

I originally thought it was an issue with the tail gate, but this turned out not to be the case.

After snooping around under the rig I found that the LH rear body mount was missing the nut and this allowed the body to SLAP the upper mounts steel pad where the two meet.

The bolt was still in the hole but the lower portion of the mount had slipped down some and was wedged between the frame and the fuel tank.

There is no real way to get into that area other than to remove the tank :eek:

There is an access hole through the lower frame rail that will pass a socket and extension.

I stuck a bar up in there and gave that a whack with a hammer a few times and the lower mount section slid back into place over the stub of the upper section that protrudes through the upper frame flange.

Quite excited now, I scrounged the needed flange head nut from the old 87 Burb and with the aid of some sticky tape, got it to stay in a wobble socket.

I carefully stuck things up in the hole and as luck would have it, the thing actually threaded onto the bolt.

A few moments later with a Deep socket on the extention, I had the little beast tight once again.

I have no idea how long that nut has been missing, but Its a good bet that it did not fall off on its own :confused:

Sure is nice to cruise down the rough road out here and not have that nasty banging noise in the rear.

Truck is almost rattle and squeek free now.

Only real thing left to do now is to work on the tail gate a little.

The swing out spare tire carrier had been bumped I think and pushed the tailgate in a little bit (can't see it unless you really look ) behind the trim panel.

This causes the window to catch as its coming up.

Need to tweek things inside a tad and all will be well.

Damned swingout tire carriers have messed up more Blazer tailgates than I care to think about. :sad:

With the warm weather upon us, I need to recharge the AC system in the beast.

Its the old 12 system and I can't seem to scare up any cans of 12 anywhere.

Put an ad on craigs and a fellow called me with a 30 pound pail for $700 :eek:

I dont think so.

I will evacuate the system and install envirosafe instead. Its cheap and easy to use..

Ahh well, such is life

Too bad your across the nation. I've got a few cans of 12 here. Still have to re-built my A/C system before they are any good to me though.
 
If you have newer hoses a 134A conversion is best. If not have an AC shop replace the rubber in the hoses. (134a leaks quick through pre 1994 hoses.) Then put in a, VOT (Variable Orifice Tube), replace the accumulator, and add 8 oz of Ester oil.

The VOT will allow the 134a system to work nearly as well as the R12 did. All for less than the cost of R12 if you can find it and you have off the shelf 134a cans every where.
 
R134a works fine with a stock orifice. I have it in my burb. The lines will be fine as long as you flush the system and replace the oil with esther oil . The problems with lines and o rings were caused by conversions done with PAG oil. That stuff eats though anything and becomes even worse if mixed with even trace amounts of 12. I have done many many many r134a conversions on just about everything. Stay away from r12 subsitutes. I used some of that stuff years ago and I had alot of jobs come back next season needing a compressor. Some of it(Hotshot IIRC) contains propane and was a fire hazard in a collision.
 
The Envirosafe is the only product I have found that works sweet with the existing system and the oil thats there.

Takes only 1/3 the amount too.

Lower head pressure and overall great stuff.

I just did not want to evacuate the system and screw around. One small can full of 12 would get things working fine.

It gets COOL now and the pump cycles, just needs a touch more refrigerant to work well.

If I dont stumble onto a couple cans of 12 I will order a pail of Envirosafe and redo things.


Missy
 
I can buy it locally, just not going to pay the huge prices to get it.

Local guy had a 30 pound pail that he wanted to sell for $400 or so.

I remember when the little cans were just a few bucks each.

I have a 30 pound pail of 134 but I dont want to mess with putting that stuff in the 12 system.

Been there done that and it's always turned ugly before it was over with.

The enviro 12 will work well, I just did not want to buy a bunch right now is all.


Missy
 
I just did my Burb. The 134a works fine, of course my stubborn ass had to pay 311$ for them damn rear a/c lines cause I just couldn't have it staring at me sayin..."You could fix me" :D
Got the last 2 of 4 left in the counrty. If I junk the burb, the lines are comin off...
 
There are a lot of parts now that are scarce.

GM has stopped stocking much of the stuff for the older trucks.

Places like LMC and such will eventually pick up the slack.
