Escort diff ratio 4.1:1
Hi All,
I have a diff centre which I removed from a Mk2 Escort with the standard axle housing which has a ratio of 4.1:1.
The Escort sedans were fitted with 3.54:1.
The Escort panel vans were fitted with 3.77:1.
Does anyone know which vehicles the 4.1:1 ratios were fitted?
Many Thanks!

Most likely 1.3 variants. Usually smaller the engine the shorter the diff..

My MK1 manual van has a 4.1:1 diff (think the tag says 4:11:1 to be precise) - I must look at changing that, too short for highway driving....

The Mark 1 Borg Warner diff was 4.1:1 as fitted to the later model Mark 1s (turreted rear shocks).

My race car was in its previous life an unmolested early Mk2 (pre July 76) 1.3 auto and had a 4.1 diff in it when I got it...
Just my 2.2c worth including GST....

Yesterday I gave the diff centre a good wash up inside and out. Got it in yesterday and car on the ground, and road tested a few hours ago. Totally amazing to hear the wind in the seatbelt next to my ear, hear the tyres running over the gravel.....and no grumpling from the tired diff pinion bearings and gear noise! The silence is deafening  Quietest BabyBlue has been in 20 years! Probably not too bad going as this would have been the first time the diff centre had seen the light of day since July 1979 on the Ford production line. I will eventually get the 3.77 back in.

Paul Truelove at Fourd Performance in Sydney will have one in stock.
I recently bought a 5.1 and a 4.7 from him, and have inspected the 5.1 after a full race weekend at Winton, and it still looks brand new.
cheers
Ted
