Hello Fello Mopar Mavins,

Recently picked up a 2010 SRT M6 car with 8200 original miles from a Toyota dealer. Looks stock except for a Magnason Supercharger.

I am an old mopar guy and have played with 60s-70s mopars for all of my adult life. I know nothing of the modern mopars.

Friends warn me that the diff is my weak link.

Can anyone tell me exactly what diff it has and the pros/cons? Axle, drive shaft issues?

This car is a lot of fun.

Thanks for your time,

Varooom

You have a Getrag 226mm limited slip diff.

The major things to watch out for:

*wheelhop - these diffs don't tolerate this well; the crush bearing clearance will change and whining from the diff is symptom of those issues.

*half shafts - on a stock vehicle, they'll be okay.

With a S/C - hard launches (esp. with slicks) will reach the limits of the stock half shafts. They'll snap at the shaft is where the failure point will turn up.

Hal H,

Thanks for your response. This will not be a track car so no slicks. Although I may go to Gulfport Dragway once to see what it will do I will stay on street tires.

Have done a couple hard 1st gear launches with wheel spin and smoke, no wheel hop yet but I will watch for it. We have lots of smooth asphalt around here, maby that helps with wheel hop.

I got an amazing deal on the car, the Toyota dealership just wanted to get rid of it. I have been able to put some money away for upgrades.

I guess I will start with a pair of axles for peace of mind. The Drive Shaft Shop looks like a good place to start.

The SRT is very comfortable in the garage with the 69 340 GTS and 70 SuperBee .

Thanks for your time and response,

So I have a 6 speed car built motor ect. Wheel hop killed the rear end and cracked the case. I would suggest the opposite. I would have the cradle bushings replace with poly bushings.
2 reasons. No more wheel hop and busted or messed up rear ends.
And axles and driveshafts are easier ( do it yourselfer ) than cradle bushings
I have done all of it except bushings and I have all the tools and will be in a few weeks
