1952-59 Ford Need Rear End Gear

It looks like the rear end gear in my 2 door sedan is toast.

Anyone have a good set they'd let go of?

 

Hi Don. What gear ratio are you looking for? Alan S. Freeman

 

I'm not that particular Alan but I guess I need to check and see what ratio is in my tudor now. Whatever it is, I like the way it's working with my 302/AOD swap. So....something close to what I have now would be ideal.

Is there a gear ratio identifier on these rear ends?

I'll almost certainly do the 90-92 Ford Ranger 8.8 upgrade that Jeff talks about...but for right now, I'm inclined to go with the quick fix...just a quick swap-out of another set of stock 54 Ford gears. (if I can find another set).

 

If was originally equipped with a straight 3 speed the axle ratio is 3.90:1; 3 speed with OD had a 4.10. If it had a Fordomatic originally it will have a 3.31:1 ****. This is all contingent on the probablity that a previous owner didn't swap axles/transmissions.

 

Thanks for the info. My car came with a 3 speed and no overdrive. So, it looks like I have a 3.90:1 gear. (I bought the car nearly 30 years ago with just over 10K miles on it, so I'm 99% sure that it's original)

It's working well with my AOD....just making a lot of noise.

I'm thinking another set of 3.90's or even 4.10's would work well with my setup.

 

Check with Joblot Automotive. He has a lot of hard to find hard parts including some parts for your axle. They have an online catalog but you have to call/fax/snail mail an order.

 

Don, 1954 Fords with 3 speed transmissions came with a 3.09 gear,while cars with overdrive had a 4.10 to 1 ratio and the Ford-O-Matic came with 3.31 to 1 gears. HRP

 

JeffB saved my bacon again.

He suggested that the large nut on the yoke might be loose.

I jacked up the rear end and had my son step on the brakes while i torqued the nut on the yoke. It was loose. I immediately took it out for a spin and 95% of the gear noise was gone. I can still hear it ever so slightly but that may be me being too sensitive...plus theres no interior, sound deadener or carpet in the car to cut down on noises.

 

Glad it worked out for you,it is something to check on the stock rears if it's not be re-torqued it can damage the pinion bearing hopefully it was caught in time.

 

I've noticed time & time again Jeff is a walking,talking Encyclopedia of knowledge,both here and over on the '54 Ford Club of America site.

Jeff and I don't always agree on cooling issues but I have immense respect for him and what he has to say,I read all his post. HRP

 

It was quiet on acceleration and then noisy when I let of the gas. In my amateur opinion, that seemed to suggest something loose, and not necessarily damaged gears.

Time (and my first, full speed highway run) will tell if there's any damage.

 

Don,have you replaced the universal joints? HRP

 

Yes....front and rear

 

Since the pinion nut was loose maybe this may be the fix: http://www.theautopartsshop.com/aut...tomline+differential-pinion-bearing+1954.html

 

Probably wouldn't hurt to replace it. Would I get at it by removing the nut in question?

 

This covers it in detail: http://www.ebay.com/itm/FORD-1952-1...-54-/230510574425?hash=item35ab803b59&vxp=mtr If you own a 1952-54 Ford it should be your #1 first investment.

 

I own it Jeff...I'll take a look at it.
