My Moms 2004 Ford Expedition 2wd 5.4L has an open differential.
The 9.75" IRS (Independant Rear Suspension) is a new differential put in the expeditions and other SUV's with the 5.4L engine (the 4.6L has a solid axle 8.8" diff).
I would preffer to put a PowerTrax in, but they dont make any for this specific diff.
I also found out that Eaton Does make a Limited Slip, but not much more information...
Does any one recommend any other brand of limited slips for this differential?
Also, Does anyone recommends a differential shop to purchase an aftermarket differential from (preferably in So Cal)?
OR is this a job that only a certified Diff shop should tackle? (I've rebuilt an axle or 2)
Thanks for any response in advance!
