LOST JEEPS :: View topic - Vibration from Hell

Guys....looks like after 1 year of trouble free ownership it is looking like the dreaded TC issue has arrived. :evil:

I went to start my crd this am ( it was -39 C this am) and about 1 min of running a huge vibration started rocking my jeep. :shock:

It does not look like the motor mounts and was even worse after I put it in reverse gear. Can I assume the TC has crapped out??? I at a loss as the jeep was normal when I parked it... Any ideas or suggestions before I go through the dealer crap?

He said it was -38 C, which is -36.4 F. Very very cold.

I will say tthat at 23k miles on OEM tires they have preformed more then I had been led to believe by some here. They are not as good as my Michelin Hydro Edge in rain, but they have been excellent on snow and ice, tire wear has been even with about 50% tread left on tire. Tire wear would have been better, but for a cheap tire I guess I can't really complain.

I am still confused as the jeep started fine the previous day ( same fuel + plugged in) and only -33 C??. I guess the warmer weather played a factor :wink:

I have had vw tdi's for years with never this issue and the same type of conditions. I will add more antigel and will prime out the air.

Any other suggestions?

Sorry for the typo, I did the conversion over at Fred's TDI forum and then rounded it off and made the typo. I also corrected the lack of starting a sentance without a capital letter. :wink:

I just giving you a hard time, I am not upset or mad.

Unless the vibration was accompanied by metallic noises, I doubt it would be the TC. Sounds more like a miss to me. Possibly fuel or air in the fuel related.

No metallic noises but huge vibration buzzing. The vibration did not come from the engine as I experimented with the throttle and the engine did not miss a beat. The vibration was really rocking / buzzing the cab and was worse when in gear.

Doesn't sound good. You may well be right in suspecting the TC. Seems like noise from the TC would be throttle sensitive though.

Congratulations, you may have discovered a heretofore unknown oddity peculiar to the liberty CRD.

Did the vibration go away as the day went on and hopefully warmed up? The engine mounts on KJ CRD are liquid filled, and at those temperatures are sometimes prone to freezing, thus shaking the car when starting.

There is a good chance that you have air in your fuel lines. Seeing that this began after it was running for a minute you likely have a filter constriction (frozen) causing the air in the lines. This can happen when it's easier to suck air in through a minor leak that to suck cold (or slushy) fuel through a frozen 3 micron filter. Try some additives before you run to the dealer.

At -36.4* F I find it amazing it starts and runs, most gassers would be in the boat from moisture in the fuel system. Try some Power Service anti gel or their 911 stuff that will thaw it out in just a few minutes. Watched a neighbor once in MI north country run out and start his truck and run back inside and about 5 minutes later as I was leaving it was knocking and then that 2 year old Ford PU spilled its gut on the driveway. It was -27 that morning and his 20w-50 was froze solid I guess, my 5w-20 Mobil 1 pumped up as soon as engine started and fuel treatment worked great and I headed to work in my 100k + Datsun PU. PS: sounds like global warming missed your area as it has ours. It was 10* F here this morning and CRD had no problem starting and it ran smoothly, (had the CRD outside to clean garage and forgot to bring it back in till I went to pick daughter at work about 6 am) thanks in part to my use of 12 oz of Power Service at each fill up. What really blows me away is the heater will put out heat in less then a mile and engine be at full temp within two miles, my gasser Dodge Magnum won't come near that kind of quick warm up.

He said it was -38 C, which is -36.4 F. Very very cold. I am surprised it started. You shouldn't be surprised it was vibrating. One way to see is to plug the thing in overnight and then see if you still have the vibration when the vehicle is warm starter in the morning after having the block heater plugged in all night. At this temp, I would guess the vehicle is starved for fuel. A diesel that is partially gelled may have just enough fuel flow to idle, but will stall if you try to drive it.

FYI, I was plugged in overnight and use powerservice antigel in every tank of fuel. I am used to this winter "thing" as I hail from Manitoba in the great white north. I am still confused as the jeep started fine the previous day ( same fuel + plugged in) and only -33 C??. I guess the warmer weather played a factor I have had vw tdi's for years with never this issue and the same type of conditions. I will add more antigel and will prime out the air. Any other suggestions?

As for the decision to buy replacement tires, was worth every penny. Sure, but I do know their limits. That said if they put the best of everything on the CRD, we would have been pay $40k plus. We have never had a traction problem with these tires, but as I said we do not push the CRD to its limits and it serves us well. On my Magnum I have Michelin HydroEdge high profermance rain tire that is also quite excellent on dry pavement. There are better choices in tires, but not for the price and they would be a waste as my Magnum is only 2.7L V6, not a 6.1L 435 hp V8 hotrod.

Heh, I wasn't really trying to correct you oldnavy I was simply trying to point out that at that temp, the difference between C and F is minimal. Joking aside, that Diesel would have to have some serious #1 blending and really good additive package to keep if from gelling at those temps. This IMO makes it easier to get a bad tank of fuel...meaning that something may have been off causing a higher gel point. I am also confused if you had it plugged in or not when this happened. You said you had it plugged in the night before that so I am guessing you had it plugged in that night too. I guess what I am trying to say is....more likely than not it is an issue related to the severe temps. Does the vibration subside when the vehicle is warmed up?

I have experienced the same thing, bad vibration when very cold. It is just the engine mounts being froze. The other morning it was -32 and it didnt happen but a couple other mornings it was below -35 and i had the bad vibration. Feels like the engine is directly mounted to the frame. Once the rpm is above 1000 the jeep smoothed out. Just another wonderful thing about being in canada.
