Rear from a explorer in a model a

Got a disk brake rear from a 98 explorer Eddie bower one axle tube is longer than the other and the pumpkin is off set dose it matter and I need 2 pluss inch wheel spacers to fit tires otherwise it hits the body (nissan maurno spares) will I have driveshaft vibrations with pumpkin of set and will it be a problem running a triangulated 4 link was going to build a truss over the top of rear so top bars have something to mount to nice and even

Get a later model Crown Vic/Merc Marquis/Mustang rear end....same 8.8 unit but is wider. Should be cheap at the salvage yard...then sell your Explorer to someone who can use it as is.

The pinion offset if of no consequence, the u-joint doesn't care if it's angled up, down or sideways, only that it's operating angle is within it's normal range.

I'm not a fan of wide rears and tires up to the windows.

The offset pinion shouldn't be avibration problem in your A as it wasnt a problem in the exploder. There are wider rears that wouldn't need to use spacers to run FWD offset wheels.

 

Thin tall tires ..... Is the crown Vic rears center pumpkin or offset?

This rear is used as a upgrade for jeeps!! They recommend a constant velocity joint in the drive shaft for the offset pinion.http://www.ebay.com/itm/Omix-Ada-DR...ake:Jeep|Model:TJ&hash=item462bdcaf78&vxp=mtr Pete

 

They just told you it don't matter if it is offset.
Nice frame ! Is that your work ?

Also notice the punctuation we try to use on here. It helps when we read your threads so we can fully understand and therefore help you with good answers.

 

Exploder has larger 31 spline axles, the crown Vic will have 28 spline axles. 31s are 30% stronger than 28. Not sure how big the crown Vic is though.

A F150 8.8 will be bigger, have 31 spline axles but not the 5x4.5 bolt pattern. Easy to re drill if needed.

 

Jeeps have a horrible drive angle, apples and oranges

 

Spare tire wheel is probably 18x4 ?
Tires are good for 50 miles. Then what's your plan for tires?

 

Yes frame is my work measure 1000 times cut once lol and ask a lot of questions .... I have a crown Vic rear at my job out of a cop car I'm going to measure up in the am thanks for the help I would like to find a rear with a center pumpkin so my triangulated 4 link looks right

These tires measure 30 in back and 27 in front they are about 1/8 inch shorter than tires from cooker they have 18x5x30 and 16x4x27 equivalent they are over 1000$ so I figured for mock up these are good and I'm at least 1.5 years away from driving so don't want good tires to go bad

Nissan maurno rears and jeep liberty fronts

That's a good plan,
Tires ain't cheap

 

A Crown Vic weighs over 4000 pounds........that axle ***embly will take anything you are likely to throw at it with a light weight Model A.

Personally, I think the importance of 31 spline axle shafts is way overrated for most applications.
Fine if an axle has them, but often not essential for the applications discussed.

That sounds about right since I have 4 inches of spacers on there

That is why I recommended it!

ray is right here im a big fan of the crown vic rear end cause they are cheap and easy to find. cops beat the hell out of them and they don't break easy.

 

Exactly. How many Crown Vic's have you seen on the side of 4 lane highways with broken axles after the cop dumps it down the median and up the other side at full tilt while coming off the gravel with the tires spun up and catching full traction on the asphalt in the other lane? If they survive highway patrol abuse in a Crown Vic, there is not much you can do to it in a light Model A.

 

Ok, I'll bite
I've not seen one on the side of the road with a broken axle,
But I haven't been everywhere at every moment and the tows come fast for a down cruiser

Now how many service bay hours have you logged in any municipal garage servicing them?
And secondly why was there a change in 2006 to 31 spline axles for the crown Vic's?
Thirdly how long has it been since you've seen a 2005 and earlier crown Vic in active police service ( not a handmedown to the building department) to potentially experience a visual of the cop dumps it down the median and up the other side at full tilt while coming off the gravel with the tires spun up and catching full traction on the asphalt in the other lane



Anyway, I'm sure it will be fine in 29sedans skinny tired A

 

The axle doesn't have to come from a Police Crown Vic (or Taxi Pkg)......the common Mercury Marquis that blue haired ladies drive is the same thing, maybe a little less common with limited slip though.

I can't believe this is a controversial axle candidate. We are not talking a top fuel dragster here.
A light weight Model A sedan will not tax this axle's capacity.......regardless of spline number.
That's my opinion and I'm sticking with it.....by golly

I'm doing the same in the rear with my A and drums in the front are you using a break booster?

 

I'm interested in this as well. Using a '96 Crown Vic rear end with discs, and Drums up front. Prefferably manual for space concerns. Anyone have experience with this setup?

 

Disks in rear, drums in front? ???

 

Yeah, I know it's not conventional, but That's what the rear axle has, and I'd like to keep the drums up front for the traditional look if nothing else. Not to mention, I've already got them.

I'm sure it can be made to work.

 

There's good reason they're not "conventional". Safety (and common sense) should trump "Tradition" when it comes to brakes, but often sadly does not.

 

There are still a lot of older rear axles available at salvage yards that will be the correct length.... Mustang,Granada,Maverick and early Ford Bronco. HRP

 

I think that's sensationalizing the issue just a smidge. This car when complete might weigh 2200 lbs with me in it. My '67 Chevelle with factory drums all around weighs 3500, and stops just fine for a street car. The rear disks can be dialed into proper brake balance with an adjustable prop valve. I don't see a problem. Especially on a car that will never see speeds over 60 mph. I'm guessing the skinny, pie crust bias plys will be the limiting factor in braking ability WAY before the binders themselves are overtaxed.

 

Thanks for the tip. I'll take a look at the local yards, and see what I can find.

 

This is the wrong at***ude. You are CREATING a safety issue.

You cannot see the problem because you either do not understand what you are doing, or don't want to understand what you are doing.

Get an axle from an earlier Explorer. They had drums.

Sell this one off.
