5.7L Hemi Problems?
 
Hey fellas
I sold my JK last weekend and I have found a nice GC I would like to obtain

My question is, does the 5.7 Hemi have any significant problems I should worry about? (Besides the fuel consumption and the ridiculous 16 spark plugs)
I really want the get the hemi, and not a v6, so I won't be changing my mind on that. I tried searching for answers but kept finding arguments about how much mpg you lose and blah blah. That's understandable, the hemi is more thirsty.
I'm more worried about mechanical and electrical problems..

So is there anything I should look for when I go to test drive? Any recalls?

Why is 16 plugs ridiculous? Gotta have the right parts to make power!!

Find one well maintained with history and you should be fine. As far as mpg I'm currently averaging 18mpg which is not bad for the beast that it is..

regards,

Mike

My old 6cyl car took 12.. stupid, and yet heavenly german vehicles.
The one I was looking at just sold. Awesome.. If I didn't have bad luck, I wouldn't have any luck at all!
On the hunt again.

Again, I don't really care about mpg. It is what it is.

If the motor and transmission are the same in a 1 ton I'm thinking it will be good in your buggy

It clunks when I put it in neutral.. There's no way this is normal, correct?

Very likely could be the front diff isolator mounts - this will often lead to a clunking being felt/heard when going between gears.

They are a pain to get at, a pain to press out, and are around $200 in parts alone (if I remember correctly).

I would have them check the condition of these bushings and replace them if need be before making an offer.

It is a PITA to replace the front diff isolator, and not cheap to have it done. Mine was done under extended warrantee. Listen for diff whining also, and drive it at all speeds, as that is another costly repair job. If it does not have full maintenance records from the previous owner, I would shop elsewhere to be honest, as proper maint. is critical on these, and costly. It might look great on the outside, but could have many issues mechanically, and cost a lot to remedy.

It shifts Great! It's just when I put it in neutral I makes that clunk.
I don't believe they have the papers on it..

Read this thread and see if this describes your problem: http://www.jeepgarage.org/f181/hard-...ear-46091.html

Not sure if the bushings and the "isolator" are one in the same, but if not this might be another source of your issue.
