Just got a call from Dodge, the whole rear end will have to be replaced. Cost is $5000.00. Good news is the 7/70 warranty will cover this with only a $100.00 deductable. Won't get it back untill early next week. Everyone be surre to change you fluid and make sure everything is OK.


2002 Ram 1500 4.7

 

Thanks Val,good advice is always welcome!Did they tell you what was wrong with the Dif?

 

Something about the clips holding anti spin clutch. Does this make any sence to anyone? The clips were in pieces.

$5K!!! For a new rearend? Incredible. Most plastic surgeons don't charge any more than that.

Must be using those valuable unobtainium replacement parts.

 

Yep thats what happens, mine goes in for surgury Tommrow. Also call you service writer back and ask them to paint the new housing, It comes bear metal and will start to rust in about a day. I stayed late tonight and painted my new one so it wil be ready for install.

 

Yea, kryptonite in a plutonium casing. Now you can say you're nuclear powered and monkey navigated.

Just playin.

 

It's a common problem with the LSD on the 1500s, it doesn't matter whether you have 3.55s or 3.92s the clips just don't hold. Nobody really knows why. The best thing to do is to replace the factory LSD with an aftermarket one.

 

Just finished mine about 20 min ago, also opted for 4.56 gears. What a difference. was a pain though because of the updated housing. Only had about.0020 clearence between housing and ring gear, had to grind down housing a little for security reasons just in case.

 

It would be doing everyone a favor (Chrysler included)
if everyone going into a Dodge dealership would tell the salesman first thing:

"I am never buying another vehicle that has a Chrysler 9.25 differential under it !"

The word would quickly filter back to headquarters.

Dodge has their choice of differential designs from Mercedes, Dana Spicer, & American Axle (GM)
all of which are proven reliable.

There is no reason to accept the troublesome C-Clip non floating 9.25 with its history of pinion bearing, pinion seal and clip failures.

If someone intend to chime in and claim the 9.25 was reliable back in the 1980s I would agree with that, but Chrysler has somehow screwed it up beyond fixing, kind of like how they ruined a proven 727 automatic by turning it into a 46 auto.

 

It's only the LSDs that have an issue, I haven't heard of any issues with the non-LSD 9.25, and my Durango with the exact same 9.25 with 3.55s and LSD as my Ram, didn't have any issues in the time that I owned it.
