Dealer Says 200 Needs a New Rear Diff??

[jhanley]

A colleague of mine recently purchased a well maintained 2008 cruiser with 126k. All records, including recent 125k service.

Today, he noticed a clunk / thud from the rear. I owned a 100 series with the same issue. After greasing the s**t out of the front and rear slip joints, no more clunk. Common problem on hundy's - I'm sure some of you are familiar.

Is this thunk / thud common on 200 series (a la 100 series)?

Are there any known rear differential failures?

I have not heard of any rear diff problems, but I have heard of transfer case issues and there is a TSB for early 200 series trucks with the chain driven transfer cases as well as a TSB for the driveshaft.

Maybe the dealership is not diagnosing it correctly? (definitely a possibility)

Here is the driveshaft TSB (which is probably what it is)

I'm sure the dealership has mis-diagnosed. I'll research the driveshaft tsb

Thanks for the link!

On the gcc spec cruisers it's recommend ed to grease the shafts regularly. Funnily enough that's what I was doing today, huge improvement. Try to see the color/state of the old grease that comes out as well as how much you need to pump before the grease overflows to get an idea if it has been running dry or the grease in there has turned into muck

Agree. Grease solved my front drive shaft clunk issue. Vibrations on the other hand they all do it. 2008 just does it more as it gets older.
