As many of you know. I have been swapping in/out my 3.46 open and 3.46 welded diffs for quite some time. It wasn't until recently when I started thinking about how it is honestly easier/faster to swap the entire rear suspension as a whole when compared to just swapping the diff. Much like what I did in this project a while back. http://ift.tt/Psv1eU
For example, rear diff removal equals: 12 axle bolts(30-45mins *this part is the killer), 9 exhaust bolts(8mins), 4 driveshaft bolts(10mins), 2 front subframe nuts(2mins), 4 diff brace bolts(5mins), 2 front diff bolts(10mins), 1 rear diff bolt(10mins), 4 sway bar bolts(10mins). Equaling 29 total areas that you need to get to with a wrench and equaling apprx. 1.5 hrs of work.
Keep in mind I do all of this on my own. A partner would speed up the process.
Rear Suspension equals: 11 exhaust bolts(10mins), 6 rear trailing arm bolts(10mins), 4 brake bolts(5mins), 2 lower control arm bolts(5mins), 4 driveshaft bolts(10mins), 4 subframe bolts(5mins), and 4 diff brace bolts(5mins). Equaling 35 total areas that you need to get to with a wrench but taking only 50 mins.
The main difference comes from those damn axle bolts. It's not so much that they are external torx bolts(even though that adds to it), but it's about having to spin the axle, climb out lock the driveline, slide back under the car, remove 1 or 2 axle bolts, climb back out from under the car, unlock the driveline, spin axles to gain access to another set of axle nuts, and repeat process over and over again.
That being said, this time around I wanted to setup the 2nd suspension(my daily driver rear-end) to be the most resistant to subframe failure and the most accommodating for NVH. The balance of both of these worlds *in my opinion* is going with completely solid subframe mounts, leaving oem front diff bushings, and replacing the commonly abused rear diff bushing with a relatively soft poly bushing. My hope is when I finally get this rear end assembled completely and installed. I can cut down on the diff whine and driveline clunks associated with my race/drift rear end which has completely solid mounts.
Once I have both rear suspensions completely assembled and out of the car I plan to take a photo of both of them and give a complete rundown of the differences between the two in terms of upgrades and driving experience.
