How-to install Axle Back on 2011-2014 Mustang V6, GT, Boss 302 & GT500

There are plenty of videos and write-ups online about how to install axle backs but I couldn't find any covering installation while the car is on ramps with little room. I don't know for sure if all the models are identical since I only have experience with the Boss 302 but I don't see why Ford would over complicate it and mount mufflers differently so I included all models in the title to make it easier to find when searching.

The first thing to keep in mind is safety. Disconnect negative battery terminal, ensure that the mufflers aren't too hot before you tackle this and wear safety glasses. I also feel more comfortable using ramps over jack and jack stands but if you use jack, make sure you secure the car on jack stands and not rely on the jack. I use Rhino ramps and so far, they haven't shown any sign of stress. I highly recommend them. If you use ramps, make sure that the tires are centered on the ramps.

Tools:

Drive extension bar
Drive extension bar with a swivel/hinged joint
Ratchet & socket set
Super grease
You might also need a flashlight to see exactly where some of the bolts are.


1 - Unbolt the rear muffler hanger mount. There are two bolts and they are tough to get to so you'll need the two extension bars to get to it and have the leverage.

2 - Unbolt the exhaust piping clamps. I had to give the pipe a couple of bangs with a hammer to get it loose due to rust. There is a small welded clip holding the clamp in place too. You may need to pry it up to allow the clamp to move loosely.

3 - Pull the stock muffler off the midpipe. This will take some moving of the mufflers back and forth to loosen. Spray some super grease on the front hangers to make them easier to slide.

4 - Once the the muffler is loose, there will be a lot more room to slide the muffler all the way back and out of the front mounts. If you have a Watt's link, you may need to unbolt the front hanger mounts like you did earlier with the rear. The driver's side has three bolts while the passenger side has two for some reason.

5 - Pull the rear hanger mount uninstalled in step 1 off the muffler. Grease helps a lot. If you uninstalled the front hanger mount in step 4, pull it off as well since it will be reused.

6 - Slide the front and rear hanger mounts on the new axle back mounts and the manufacturer supplied clamps on the exhaust pipe. If you didn't uninstall the front hanger mount in step 4, slide the rear hanger mount on the new axle back and then slide the front hangers in the hanger mounts while they are on the car.

7 - Install the rear hanger mount on the car first. I found this to be an easier way since you have a lot of flexibility to move the front facing side around to get it to fit on the midpipe. If you uninstalled the front hanger mount in step 4, leave it uninstalled for now. If you didn't, you may need to untighten the bolts a bit to give yourself more room to move the exhaust around to get it to fit.

8 - Once the axle backs and the midpipes are fit properly, get out from under the car and take a step back to look at the exhaust tips. You may need to fiddle around with the axle backs a bit to get them centered in the diffuser cut outs.

9 - Bolt the front hanger mount back in if they were uninstalled. Don't tighten until you recheck that the tips are still centered.

10 - Tighten the exhaust clamps to manufacturer's spec and reconnect the battery terminal.

11 - Start the car up and enjoy!

Michelin Pilot Sport Cup 2's vs Bridgestone Potenza RE-71R's

I never thought I'd ever run Michelin Pilot Sport Cup 2's on my 2012 Boss 302. The cost is astronomical and they are supposed to last the least of anything comparable. So how did I end up with (nearly) fresh Sport Cup 2's? A complete fluke. I came across a lightly used set with only a few hundred miles and no track time; 305/30/19 takeoffs from a GT Performance Pack Level 2 (GT PPL2). I knew my 71R's were getting very worn before the season started and likely wouldn't last the whole season, even this short one. The price was far better than a new set of RE-71R's, a little more than half, and local Time Attack rules (Canadian Automobile Sport Clubs) recently made 180 and 200 TW tires equivalent, meaning no PAX or PIP point penalty for going with 180 TW tire like the Pilot Sport Cup 2's. I have been very curious about how PSC2's compare to RE 71R's but I stayed away due to their being painfully expensive and, up to last year, their 180 TW rating would

GTR vs Evo X vs STI: which has the best AWD system?

A few weeks ago, I made a post explaining  mainstream AWD system types and how they compare , pros and cons, etc. including some simple diagrams to show where the power goes and how much. As promised, this post will focus on specific cars and what AWD systems they use, especially ones that that have more or less been defined by their AWD systems, and the best place to start may be with a bombshell; the Nissan GT-R. Nissan GT-R (R35) The GT-R has built a reputation around having monster traction and very approachable performance, thanks to its AWD system - Advanced Total Traction Engineering System for All-Terrain (ATTESA) - and what it can do for you. But the GT-R doesn't actually use the most mechanically sophisticated type of AWD systems discussed in the previous article, namely a "true" AWD with a centre differential. Instead, it uses a clutch pack to transfer power. RWD-based clutch-type AWD schematic - Rams Eye The Track Guy © The R32, R33, and R34 Sky

How would a Mustang 3.5L EcoBoost compare to the 5.0L V8?

Ever wonder how a 3.5 litre EcoBoost might fair against the 5.0 litre V8 in the Mustang? Of course you have. Ever since Ford dropped it in the F150 (and perhaps well before), everyone has been wondering how it would perform. There are basically two camps; those who think it would be awesome because of tuneability and power potential and those who think it means the death of the V8 in the Mustang. If you are in the latter group, we seem to be good so far with continuous upgrades to the 5.0 litre Coyote and the brand new Shelby GT500 which still uses a supercharged V8 as it has been for over a decade and multiple iterations. But what if... Well, it seems we are closer than ever to finding out the answer to that question. American Trucks recently got together two crew cab, short box, 4x4 F150's but one has the 5.0 litre V8 and the other has the 3.5 litre EcoBoost V6. There has been a few comparisons between 5.0 litre and 3.5 litre EB F150's, but this seems to be the most di

Bridgestone Potenza RE-71R Track Review

2012 Boss 302 on square 305/30/19 RE-71R's at AMP - Graham MacNeil © For better or for worse, I have heard and read so much about RE-71R's. Everyone swears by the grip but complains about the wear. Generally speaking, the pros are: 1. They grip as well or better than most R comps. 2. They don't wear as quickly as R comps if driven occasionally on the street. 3. They work better in the rain than R comps. The cons were limited to overheating quickly when used on track (being an autocross tire) and wearing too fast on heavy cars like mine. In the popular 200 TW category, they are faster than the popular Hankook RS-4's and BFGoodrich Rival S's according to published Tire Rack Tests. According to plenty of reviews, they are also faster than well established R comps like R888R's (which don't seem to work too well on heavy cars anyway) and the venerable NT01's. But I was still hesitant for a while until I talked to a tire tech support gentleman
