[XR7-4.6]

The mark VIII (and any DOHC) alternator is thinner

Yes! The Excursion was not lighting the left rear and when in service bay it worked fine. As they were backing it out and stopped I noticed the right was lit and left was not. They were like well I'll be damned. They were suprised but immediately went to the mfs.

Played with it over the weekend, began troubleshooting in a failed state. It wasn’t until I touched the socket that it started working. Hmmm. Then couldn’t get it to fail again. I replaced the bulb with a spare I had.
No problem back and forth to work today.

Our alternators are "3G "type, for my 4.6 cars anyway. What is the mark alt called?

The subframe isn’t a brace…. As intended. But if it’s solidly mounted on metal bushings is effectively a solidly part of the unibody structure, whether it benefits it substantially or not. I will firmly say though given its steel is literally twice the thickness of the unibody stampings it’s probably doing more than adding a few twigs between the LCA mounts.

There’s still the question of what I asked though; what problem would it solve? Beyond the challenge of maintaining composure from engine torque the IRS is far less critical when it comes to maintaining geometry than the front suspension and aa far as I’m concerned if you’ve got stiff bushings, good shocks and springs and an Addco back there any piece of brace you’re adding back there is ballast at best.




That’s not true, well designed subframe connectors undoubtedly work, however I find *bolt in* connectors(which given these cars fuel tank are inherently stuck with) inherently compromised and a net zero or negative in vehicle performance for the weight and irritation they add.

As to your question of what it will solve, I would THINK that it might add to the overall structural rigidity of the whole car specifically the rear end, aiding in the twisting forces the car sees going over bumps and such.

I see why you don’t like bolted in braces, but let’s say with today’s adhesives and epoxies would you think that adding some adhesive in conjunction with the bolts would se the braces actually do something now that they aren’t just held in place by the bolts only??

If it has a black plastic cover on back it is 4G. It is not same as 3G as the brushes and regulator are made different. Here is a lengthy list of which is which and where to find them.
