Pardon my ignorance, but by shocker you mean shock absorbers? No I didnt. What will loosening the front cradle round mounts nuts do? Will the cradle then pivot?

Aussie strikes again, how good are we??

Yes, shocker is Aussie slang for shock absorber, and I seriously doubt that the drop angle of that cradle will have any affect on them, but if its binding, better to play it safe.

The front bolts will allow the cradle to "pivot", and prevent tearing of those round mounts, another job you really dont need right now.

Brake hoses is another item, but I have NEVER touched then for this task.

Another crazy thought, caffeine hit just peaked.

On some of the 6cyl cars I have the pleasure of sorting, the front section of the sump is almost touching the cradle, coz the engine is NOT set correctly on its mounts, and at a pinch, the angle MAY have bound the engine at that area, take a look before forcing anything, that cradle should easily drop far enough to get your hand in from the front to that "stupid" bolt on that V mount.

Grant! Thank you! Thank you! Thank you! Lossening the nuts on the top of the shocks and lossening the front big bolts allowed just enough room to slide the rear broken mounts out. A LOT A less work than removing the rear trans mount again. Now to slot the new ones and back together again. You are the best!!!!

Job done!! Grant - with your permission, I'll take your document and make a few additions, observations, etc, that will even clarify it more?

Took it for a test run. Seemed fine for a mile or do. Shut it down to get ice cream. Then when starting out, could feel what I think was the rear brakes sticking in both forward and rearward. Definitely sticking the rest of the way back home (1 mile). Then, within 100 yards of my driveway, I could feel it release. Definite smell of brakes when in the garage. Scoped everything out with a flashlight and don't see anything untoward. Guess I have to keep my eye on it. Emergency brake has never worked very well. That project is sometime in my future.

Alter away, no issues.

The Park Brake is a Mongrel, and I have never used them on any Inboard Brake Jag.

If they have released, then dont use it again until its fixed, or it will really jam on, and even the flatbeds will have trouble loading it.

The P is just fine.

Seizing rear calipers is an issue up there, hear it too often, as I have never had any seized calipers on any Jag.

Okay, I've modified Grant's excellent writeup, updating with my experience and recommendations. Took the car for another test drive last night and all was okay, but on the way to work this morning the rear brakes started locking up again. Turned around and took her back home. Have to put back up on jack stands and see what problem I created by lowering the front suspension cradle. I know it's the back brakes locking up though. Can see the smoke. I'll update when I've found the solution. If the updated Word doc does not attach, would someone please let me know how to attach it. I went through the same process as a picture file, but it doesn't look the same.

Up on jack stands again, and inspected all the brake lines, both flexible and hard, checked EB. All seemed okay. Put it in drive and started pumping the brakes. The brake pedal went to the floor!! I then thought master cylinder but it's new about 6 months ago. Pumped it a few more times - same thing. Then saw a big puddle of brake fluid on the garage floor under the front right side. Saw a grape sized bubble in the flexible hose and a split in the hose near the entry of the caliper. Glad THAT didn't happen out on the road! Got new SS braided lines from SNG Barratt (2 fronts and 1 rear) and will install them over the next couple of days and bleed the whole system. Let's see what that does. I should have done that job a long time ago. Shame on me!

Hey Vetran, I own a 1989 vanden plas 3.6L engine. I am attempting to replace my oil sump gasket. Can you tell me to what the engine support bar chains attach to on the engine to support it?

thank you very much for your time!!

Sorry, I never used an engine support bracket. Haven't needed to lift the engine yet. LNRB has a post here somewhere though.

One bolted to the front of the head, other to an intake manifold hole with a longer bolt.
This was ONLY to suspend the front of the engine. Rear suspension point(s) still intact.
