RP has additive in it already. As for the OP. You can and should do the TB, spark plugs (no wires on the 08, its just a coil pack and it doesn't need to be changed), the tranny flush (dirtydog has a write up somewhere), and the diff fluid. You'll easily save $1000+ by doing it yourself

 

Yeah I made sure and asked around on here before not using the friction modifier with the RP in my diffs. I actually bought it just in case, but returned it after test driving and all without any chatter. Dirty had done this and gave me some good info about it as he had not needed it as well.

 

well here is my build data, i don't see where it says anything about LDS?? can someone confirm or deny?? I think i am going to try the differentials myself. I'm going to get mobil 1 synthetic 75w-90 for front and 75w-140 for rear. what RTV should i get for sealing the lid back on? Also, do i need to worry about the clips i've been reading about on an 08 1500 hemi?

Nope. You would see a line that mentions "Anit-Spin Differential" if you had the LSD. Which is weird that a 4x4 doesn't come with it. But you can always add an aftermarket one!

So to answer your ? You don't have to worry about the C-clip in your rear.
Its also funny how they put in a HD front axle and a LD rear axle in your 4wd WTF

 

Did you take that from a 2500 build sheet MoparPaul?

 

so are there any concerns i should have with winter driving and no LSD? is only one wheel going to spin in snow/ice?

 

Yep. You pretty much have a 2WD. Its just one up front and one in the rear lol

 

So i understand that in 2wd that only 1 rear wheel will spin, but are you saying that in 4wd high only 1 front wheel and 1 rear wheel spins? what about 4lo?

 

What he means by that is yes you have 4wd but you have open differentials front and rear. So if slip starts occurring which more than likely if you are needing 4x4 it will, then only one tire on the the rear and one tire on the front is going to be spinning and trying to move the truck.

Basically just like even if you had a stock rear lsd, the front is still going to be an open differential, which has the same thing happen in the front. You just happen to be unlucky enough to have open front and rear. It boggles me that they would do that in a 4x4 but if it makes you feel any better, im almost positive the 06 I just bought yesterday is open diff front and rear
