    I recently broke my differential on my 2000 v6 I got a used rear axel for like $370 but it was a 7.5 fitment I don't know if I needed a 7.5 or not. If I have an 8.8 driveshaft how would I go about connecting them if it's possible. It's not to late to cancel the order but I would have to wait...

    Okay guys and gals. I hope I’m not learning an expensive lesson. I swapped in an 8.8 into my 83 fox. I decided to reward myself with a pretty b&m diff cover. I liked the fact that it had drain and fill plugs. Problem is clearance between the spare tire well. Is this typical with these types of...

    Hello I’m having trouble w this could yall help, I have a 2006 Mustang GT and I recently had to replace the whole differential, I got the same gear ratio and all that but the pinion flange on the new used differential seems to be a aftermarket one because it’s short and the driveshaft can’t...

    Recently i got a quote from a shop for a 4.10 gear installation with parts included, $750. I was considering going with 4.30 gears to get the most out of it but not go crazy with it like 4.56s. Is there anything that would change the pricing between the installation costs? 4.30s rather than...

    Hey there, looking for some advice on what parts I might consider replacing in my 2006 V6 while I have the rear end apart. I'm installing a limited slip diff and some 4.10 gears. I got the install kit with the bearings and gaskets. A guy I talked to about doing it mentioned something about...

    Alright, a couple of months ago my pinion seal failed. There was oil that sprayed all around the diff, even onto the exhaust pipes in the area, and the underbelly of my car. That was about 6 months ago, and probably 10,000 miles. Today, i had my car in the air replacing the rims, and i noticed...

    Hey all, does this seem like an 8 inch Ford rear end to you, because it does to me. Going to upgrade to 3.55 gears and wanted to of course make sure before I bought them. Car was originally a 6 cylinder but now has a 351W and I think the previous owner installed a beefier rear end. Thanks.

    My 2013 V6 had the usual axle vent leaking. The axle was wet, I wiped it dry, and all was well. No problems. With my 2014 GT, however, this amount of leaking doesn't seem normal, right? My growing concern started yesterday when I noticed there were fluid/oil marks on my driveway. I had never...

    so i recently had an Auburn limited slip installed in my 05 V6, and my speed shop recommended buying a Gt rear for her because the differential can be rough on the stock one. do you Guys recommend anything else and where can i get a good one from?

    I just bought an 03 gt convertible that 's had a ton of work done to it and when I went to change the rear diff fluid there isn't a tag to say what gears it has in it. The only tag on it says it requires 75 40w full synthetic fluid only. So how can I tell what gears it has or if it's a different...

    Hi folks, I have read so many great and helpful posts on this forum that I thought it was finally time to share one of my own challenges and hopefully find help. I recently acquired a 1965 mustang convertible, sprint 200 6 cyl automatic. We loved it, researched the dealer and bought it...

    Hey guys, I am trying to figure out what my differential gear ratio is. to do this I am marking my drive shaft and tire and spinning it accordingly to determine the ratio. Here's the problem, I have an aftermarket aluminum drive shaft (either 3.5 or 4.0) so I need to compensate for the extra...

    Greetings all, it has been awhile! This website has been an amazing resource for me, and I still read the GT Tech section almost daily. FYI, I have a 2011 Mustang GT. That was my daily driver for almost 2 years, and I have driven it once every 2 weeks for the last year. I had a mechanic install...

    Hi All. I bought a really nice, clean 2001 GT late July! My first GT! It's got 49K and a manual transmission. The interior is a time capsule with not a spec of dust. When I test drove it from the seller almost everything was perfect, drove straight, great brakes, clutch is fine, etc., but it...

    have been searching for hours and cant seem to find the answer. Spool with c-clip eliminators and 31 spline axles meant for c-clips? will that work or do i need to buy special axles without the cut for c-clips or what? Thanks.

    I love these gears that were installed in my 08 bullitt. Big difference from the 3.73's. Anyway as you guys probably have already heard, they're making a humming sound at pretty much all speeds. I've already tighten the pinion nut a little bit...didn't work. Had the backlash tighten a little...

    hello everyone, im new and I just bought a used 98 mustang gt. the cars is in pretty good shape but i have noticed that when im cruising and on the gas ill hear a whirring noise coming from the back end. I don't know if it the differential or a bearing or something of the sort. I know i need to...

    Howdy folks. My 1971 Mustang started making a new sound today. Kind of a thumping sound. It's kinda weird and semi-random. I thought (and was hoping) that it was someone- I mean... SomeTHING in the trunk. It's a low thump that almost seemed like it might have been the sound of my wheels hitting...
