So... when did the WK1 switch to a limited slip differential??
In an effort to collect some data points for arguing with the Dealer about putting Limited Slip Additive in the differentials unnecessarily, I called the SRT Consumer Assistance line.
After tons of fumbling around trying to answer the question on their end, they ultimately indicated that my 2010 WK1 indeed has a limited slip diff and would need the LSA fluid put in. (insert foot in mouth)
I've read lots of postings here and on wkjeeps that we do not need it in there. Does anybody know what model year this changed? Is that right!?!

ELSD axles are standard with Quadra-Drive II. SRT8 axles DO NOT require Limited Slip Additive.
thats why i do all that i can on my own. the dealers are selling vehicles they cant even maintain correctly!! what a joke they are. only dealer i would truxt is one that does performance work like a hemishop
That's what's fascinating.... From the SRT Team!?!
Granted the "Quick Reference Guide" the dealer uses (I was give a print out, and its VIN based) is not clear on if it should be added or not. There's two rows listed, one with footnote to use LSA and one without the footnote. So I can see where somebody could have a question and lean toward adding it in. Good news it doesn't look like it hurts anything, but it was in the price and the job wasn't done "right".
Still baffling that the SRT Assistance line says otherwise?!?!
Find a trusted INDY if you don't want to do it yourself. You will end up with tranny/TC problems 5,000mi down the road. You will become infuriated with the same peope that are, pretty much, telling you they don't know how to service your vehicle. Listen to your forums members, as they can save you a lot of pain and $$$. Hope you get everything taken care of.
the fluids are really really easy to do if you have a jack jackstands and some wrnches. the tricky one is the transfer case wich is still simple just gotta get the fill right.. NO ADDITIVES!!!!
Would go DIY, but wanted the serviced registered with the dealer as I'm still in the drive train warranty. The job looks to be very straight forward. I haven't tracked down a 14mm hex yet. I picked up the 10mm hex at Sears HW, but they didn't have the 14mm. Need to check an auto parts store I guess.
