Need Some Rearend help/info - 2003-04 Mach 1 Registry Owners Club

Twitch · 01-08-2021, 06:26 AM

Have an 04 mach with stock rearend except using 4.10's.

I have been trying to locate new spider and side gears and had no luck so went to local Ford and he told me that for him he cant order because that gear carrier is listed as non-serviceable.

I have googled and googled for what I need and find nothing.

So anyone here know if I cant just buy the spider and side gears or and I gonna have to drop around $500 for the whole diff carrier?

Thanks for any info.

Those are the parts I need but I can find them for the Mach. I contacted LMR about those yesterday, they will not fit the mach and ford parts confirmed this.

I just need to replace those parts in pic but from what Im seeing I gonna have to do the entire carrier.

BTW the white mach's are my fav color

I thought the SRA's for the GT's and Mach's were the same..?

So everything in the rear end is stock, but that you have 4.10s is all?

Yes, I have FRPP 4.10's.
As for the GT vs Mach I thought they were the same also but the Ford Parts guy says on his PC that they list them not compatible, LMR also confirmed this and referred to Ford parts.

I find it really odd that none are available for the mach, they do come out of the carrier since I removed the entire carrier to replace all the bearings and everything in there.
Thought my original rear noise I had was just bearings but its those gears.

I just cant find what the difference are between the mach and gt anywhere.
