Needed a rearend for my coupe so I went to ecology and picked one up for real cheep. After being so frustrated from trying to get it out with a crappy assortment of tools, I finally realized (when I got home) that what I thought was a vent line was a cable with some wires in it(2 I think) and there is a hump in front of the pinion , so I am pretty sure it is a 2 speed. Anyone ever heard of these or know how to run one? It was out of an early 80's, possibly late 70's lincoln mark 5 or 7 or something...
I remember that the Cougar Eliminators had a 9" 2 speed rear. I'm not certian as to how it was actuated. I'm sure it must have been available in other "ford" products but not advertized like the Cougar.
V8 if you can get some photos of that rear if it is in fact a 2 speed 9" I would be grateful. I could even use them if they are old school paper photos. Having done a ton of research on Ford 9" rears and have never seen a picture of one.
Are you sure it's even a nine inch? Maybe it's one of the 9 3/8" rears that came in Lincolns. As far as two speed rears in Cougar Eliminators... I think somebody was pulling on your leg. Dan
The two speed 9" rears were availible in 68 Cougars, one year only. Didn't sell well at that.Aluminum case too. I have never seen one in the flesh, but have seen pictures.
Here's the story... doing a search of cougar & two-speed. The first Eliminator for the street in a sense was strictly a one-off car to test the market and to test the components proposed to be used. It was run around the show circuits and let out to the automotive press. It really was a beauty! Came with all the goodies necessary to turn heads at the strip and on the street. It had a dazzling Radiant Sun Gold paint job, an air dam up front and a moulded spoiler in the rear. A CJ 428-4V ram air engine going into an automatic transmission got the new Cougar a moving. Is this where the name for the first Cougar Eliminator came from? This is Dyno Don Nicholson next to his fiberglass 68 Cougar. Dyno managed to get a new world record for his 1/4 mile efforts out of this very Cougar. The car went 7.48/ 191± back in the 1968 season. 427 SOHC The most unusual item about it was not up front, but what was in the rear. The axle to be exact. The rear axle was a two-speed. One ratio for racing and one for riding. The axle, or third member, was made by Dana-Spicer and they called it the "Streep". The engagement or selection of ratios was controlled from inside by the driver. The first Eliminator further came with an XR-7 dash, high back bucket seats in black vinyl with hop sack fabric inserts and mod red and orange stripes. The sides of the car carried a long thin white stripe, later to be standard on the production line Eliminators. A hood scoop for the ram air package 428 Cobra Jet completed the visual image of the new Cougar. Clearly it states the rear end was a one-off. Dan
[ QUOTE ] It was out of an early 80's, possibly late 70's lincoln mark 5 or 7 or something... [/ QUOTE ] Did it have disc brakes? All the big lincolns back then had discs on the 9" - if not, you probably got something else & I'll bet that something else isn't a 9" Assuming there are wires going in there, I'd bet on something other than 2-speed. There physically isn't enough room for anything - even a small planetary gearset wouldn't fit in a "hump" - probably some kind of electronic pickup/sensor...just a guess though I've been all over the world & parts of Georgia & I ain't never heard no shit like that - 2-speed 9" Love to have one though!
Sounds more like a sensor for an anti-lock brake system to me. There is a thin wheel attached to the ring gear and a sensor is screwed into the housing to count windows in the sensor ring to determine vehicle speed and whether your rear wheels are turning or sliding...sends a message to the abs brake system ecu and...........well, it ain't a 2 speed. It's prolly just the sensor wiring.....
Old Beet might still have one laying in the yard, it's a sensor of some type. Maybe PM him. I remember I never seen one like it before. We started laughing like we did when we saw a sledge hammer with a power cord on it, like WTF? Needless to say, he put a "non-electric" 9" in his 49 Merc.
General Motors had a 2 speed rear end. RPO code is FA1 and FA2. Both ratios were the same. 4.88/6.94 They had to be for large trucks. Also, some small busses had two speed rear ends in the 60's.
I'm with the guys...NO room inside for a 2 speed! HAS to be a sensor and the most likely thing is Anti-lock. Sure it isn't from a truck that had an aftermarket Electric locker added? I know one was in the works (didn't think it was actually even in production yet)...BUT...ya never know your luck in the big city... I'd still guess a later rearend with antilock. Anybody have access to a Lincoln wireing schematic to see what the harness runs to on the rear axle?
I'll have to do some research on this! When I was down in Ocala Flordia I stopped at don Garlits place... he had a 32 ford with a two speed rear in it! I dont recall the name, but it had dark paint was a convertible and had a red interior... thats all I remember about it though
Hmmmmm, well, I will definately have to get some pics of this mysterious object, but I am pretty sure it's a nine inch because it looks exactly like my buddies and had a very long time hotrodder tell me it was also, and I am not stupid enough to mistake a sensor for a two speed, It is definately a gearset or something because it has a big thing in front of the other thing on the thing(well I'll just have to get some pics. should have some in a day or two, stand by and wait for them...
It has been a number of years, but I am pretty sure Lenco built a two speed that mounted on the pinion of a nine incher. Never saw one except in a brief magazine bit, but I suppose it is possible that you have one..... It was a planetary setup like a Lenco racing transmission. I am certain they are rare, but you have something, right?
sure is, I guarantee it is just crap because nothing I get is ever good, or if it is it's broken...like last week, bought a parts truck for my 40 and turned out to have a columbia in it!, the fucking axle was bent and unusable(tube and all)so, we'll see....
Didn't the Lincoln come out with a electric anti spin. It comes to mind that they had somthing on that order.
If you were putting this into a car that already had a 9", would you need to shorten up the existing driveshaft? Bill
In the late 70's Lincoln was experimenting with both 4 wheel discs (an option on the Mark V's - which had the 9") and traction control/primitive ABS...that may be the connector you see. At any rate, those rearends were wide as hell...and had crappy gears stock...
Geez...Thats where a planetary would have to go for two speeds! Big enough too! Not in the right location for a locking diff...so most likely thats out. (BUT...It IS a Ford...Soooo?!?!) Antilock speed sensers would mount in the crown gear area...you would figure anyway...not on the pinion. Sure wish I had that home so I could pull it apart! THATS velly interestink!!! Electric planetary lockup....how would that work anywho? What else could it be!?!? Looking at it again...I'm not sure what I'm seeing! I can't tell where the 9" stops and the extension begins... IS there an extension? That pic is rough! BTTT anyway. Bill
Ya! I just looked a one I got. Out of a 74 Linc Cont, 2 wires run to the pinion area. I thought it was speed O or for Cruz control, More than likely its a 9 3/8 inch Posi. It sure ain't a 2 speed..........OLDBEET
would the wires make it possibly go in and out of posi mode or what? I think I will just go with a normal 8 inch so this ones probably going to get disected so I can figure out what it is. Sure is friggin heavy enough.
Although the pic is crappy, it is NOT a 9" I believe it is, as some have surmised, a 9 3/8" rear. Look at the horizontal reinforcing side rib on what would be the driver's side - see how it isn't straight, but turns down? I think that's the tell-tale sign of a 9 3/8" rear. A 9" center section will bolt into that housing just fine & if you've got the right # of splines, your existing axles will work. The bulge is interesting nonetheless - would love to see a clearer pic of it. Perhaps some closeups & if you dissect it, be sure & take pics!
