Isn't it one of those fail safe ideas - loose the nut and you won't loose the bolt, or completely separate the subframe from the car?

Figured that to be true and maybe a little assembly line efficiency peppered in too. Faster and simple to install at the factory if both bolts already in place.  

 

Either way, it's a pain in the ass to replace the mount with the subframe up in the car and them bolt threads facing forward.  

 

If you look closely at the shop manual depiction-the long chassis bolt (#8) is obscured for reference of location. It says to me it's clear there has always been an issue with assembly while on the car.

The instructions in the shop manual say to remove the long knurled bolt first (#8).  Then you don't have an issue with it being in the way.

Dammit! why did you show me that?

I have those blue manuals but did I ever look at that section, no. 

Driving that bolt up and out sounds like just as much of a pain as is to do it the other way.  

 

all I know is I'm reinstalling with the bolts in the danger zone.

 Go for it, Maverick. New lock nuts, locktite, correct torque, check 'em periodically.  I'm sure they'll be fine.

I have to look at mine.  I may have defeated the safety feature too.

 

Just looked,  I'm good to go, nuts forward!

Didn't look. Felt by hand - yeah - nuts are front.

[Buckeye]

If you decided to go with head bolts towards front then add 10% to torque specs value. Me, I will do it they service manual is written.

So let us know if replacing those took care of the thump!

Funny you ask, it did not.  I am gonna endeavor to look at the exhaust maybe hitting the tank or subframe or perhaps even a rear shock might be blown and froze causing the spring to rattle. Bit by bit is what it takes to sort a car out.

My last mile on that one was the center muffler on the subframe.  It’s a game of mm.

I little more intel to tell ya, should you still care to read this.  

 

The rear muffler rubber hangers are drooping and with a little effort can make the tail pipe bang the tank and tail panel. Now that being said, there is no evidence in ways of scratched paint or exposed metal to prove this is the culprit. I went and shored up those soft rubber hangers to where the muffler can't possibly bounce off anything.  Still the damn noise can be heard.  One thing I do notice is that either something is very loose or floating around inside the tank makes a sound. However, it's more of a hollow note rather than a thud when the car hits a bump in the road.  

 

Question: how much vertical movement is normal in the rear subframe mounts?  I can with a prey bar generate about a half inch of travel up and down. Again though, no evidence of metal on metal.  

 

Help me Obi Wahn you are my only hope.

Is there a spanner forgotten under seat?

Are the plastic half moon filler pieces still there?

Nope, that's how I got most of my tools in the beginning.  I could use a 5/16" though. Might have to pick up an American car for that one.

Yes'er 

 

I might have to check the jack and lug wrench although I was certain they are locked down.  

 

It's like trying to figure out which smoke detector has a low battery.
