Engine Problems due to Lift????

Hi, I have a 2007 JK 4-door. I have a four inch lift on it and my engine threw a rod out and now I am being told by the dealer that I need a new engine. I have less than 41,000 miles on it. The dealer says that it is due to my lift as this causes additional strain on the engine. I NEVER had a single caution light on my dash board. Does this sound correct? I find it hard to believe that I should have to replace an engine at 40,000 miles due to my lift. Any thoughts would be greatly appreciated.

Thanks!

Since you have a 4 lift then you probably have either 35 or 37 tires. You never filled out your profile so its difficult to give an honest opinion. Do you have an auto or manual? What gear ratio are you running, 3.21s. 3.73, 4.10s, 5.13s or 5.38s? Are you one of those people who think they have to floor the pedal while going up long grades and or with a head wind? Did you ever change your oil and do you keep tabs on it between changes? What were you doing when it threw the rod?
You see that there are a lot of questions that need to be answered. Much more than I listed here.

what hes talking about is how much harder the engine has to work to pull larger tires. i assume you have bigger tires if you have a 4" lift. perfect feasible explanation, but pretty rare.

Most likely the OP never changed the oil,did extended drains,did not regear the diffs for larger tires,or hit something offroad and punctured the oil pan just to name a few things,just pic one or 2 or 3.


There blaming the lift but if he does not have receipts showing oil changes with the correct oil he's SOL anyways.You do not need every receipt,but enough to show a trend,does not need to be shop invoices either as a receipt from wallmart with "6qts of 5w20" and what ever filter is clearly stamped on there.

I do have 35" tires on it. I did regular oil changes but I was over by 2000 miles for my last oil change (so I was at 5000 instead of 3000) I have never taken off road but I do punch it up hills. It isn't 4wheel drive. Help!! I don't feel like I should have to pay $6100 for a new engine at 40,000 miles.

If you've got the records for your maintenance, you are on solid ground. Either find another dealer or contact Chrysler Customer Service.

Good luck.

I have to ask though. What warranty do you have? The 3/36 is gone now.

In my opinion the JK engine system will not allow it to run above its limits!
Take the electronic throttle, When you're in a high gear and put the peddle to the floor the response is no different than if you eased the peddle to the proper position. The old systems with a cable would open the air intake to the point of engine knock and catastrophic failure.
The towing rating on a JK Unlimited is 3500 lb!
Nobody can honestly say that stock gears and 35" tires adds more stress to the engine than a 3k lb. trailer!
The oil change shouldn't be an issue because the manual states 5k or 6k miles between changes.
I think you need to do some more research and find a way to contest their decision!
Good luck

Why not call AEV and find out what they do with brand new 3.8's that have been removed for the hemi's. Maybe save a little money.

All I will say is if they dont want to fix it under warranty, then dont let them fix it when your paying! Used low mileage engines can be had at a decent prices now-a-days and any decent mechanic can swap a engine... I wouldnt be surprised if you can get the whole thing done for under $2k depending on how hard you want to look. There are lots of salvage yards online, hell I found a 5.7l hemi for $2k with 20k miles on it....

In my opinion they should replace it under warranty, what good is a lifetime warranty when there is nothing to use it on. Problem is it sounds like you will have to fight him for it...Try taking it to another dealership, prolly would be worth traveling out of town if you have to.

edit
I just noticed you have a 07, unless you picked up a warranty package somewhere you might be out of luck in that department.
