Yes it is. The difference is amazing when the correct rdu is installed

The way I understand it going to a taller tire will affect the speedometer and odometer. Is this not correct

Were you able to update the circumference in the ecu when you switched to the larger size on your 2020? My local dealership is saying on my 2021 it's a50/50 chance of being able to update it. I'd like to know before buying the tires

Has anyone had an issue updating the circumference in an early 2021 for size 295-40 R22 in the ecu? My local dealership is saying there is a 50/50 chance of being able to update it due to it being and earlier model. I'm getting ready to order the tires and want to make sure it can be updated.

Looks great! Looks great! Have you had any issues with rubbing? I just ordered a set of 22x10.5 +30 offset wheels and are planning on using 295/40R22's which are a shorter tire than you are using. Also have you towed with the eibach springs and had any issues? I'm trying to decide between the...

Just saw your reply. I'm back to bone stock as I'm on my 4th rear diff if you count the original. The original RDU is the one I had the Steeda front pinion bushings, subframe spacers, and RDU brace on. That was the one in my original post that had been replaced. The dealership reinstalled the...

I'd wonder the same thing. Isn't that what gets replaced with a solid shaft

Those are all good questions. I always considered 8.8" rdu's to be good units. The one in my 95 tbird is still going strong

Mine did ok with the S606D, the first replacement, it just didn't last very long. Hopefully this S604D does.

You're welcome and I hope no one else had to go through this. Hopefully Ford gets its shit together soon.

Ok so my ST is FINALLY fixed after 2 months and 2 dealerships. I had to take it back to the original dealership to get it fixed. I gave them the info from the second dealership about the rdu being the wrong one. Neither dealership could find the part with my vin# as the search would say there...

That is actually the first rdu they put in my ST after the original went out. Then after about 700 miles i started getting a vibration when accelerating and a loud howling noise so they replaced it again with the S602D and that's when the bucking started. Then they said my transfer case was...

That's what i finding out, the S602D is for the Platinum and 3.31 gear ratio.

To the guys that have had the wrong rear diff installed, what was the part number of the correct one that was installed? I'm getting conflicting part numbers from different dealerships? I'm being told S604D by 2 dealerships and S602D by 2 others. The S602D is currently in my ST and that's...

That's what I'm thinking because it does buck like a bronco. I'm going to the dealership again tomorrow and hopefully that's the conclusion they come to before I get there
