Front wheels wobble.

I did a search about "Death wobble" on the forum and was reading some of the threads, so I understand that this is not a unique problem.
In my case it happens only if, lets say, I am in 3rd gear and due to some reason I slow down. I slow down till the engine starts jumping and then I go into wobble.. The steering goes crazy and the front part jumps side to side.

If I shift down when my speed decreases then its just fine, is this normal or do I have tire balancing issues or any other thing ?

oh btw, I start the jeep in the morning and just put it in reverse out of my garage and drive. Do I need to heat up the engine (Let it run for sometime?) ? Can a cold engine cause wobble?

sorry for the stupid questions..

Thanks in advance.

I had a similar wobble with my jeep, that was a combination of out of balance tires and wheel bearings going out. New tires/wheels and wheel bearings have eliminated my problem.

Lift the tires off the ground and see if you have play in them that you can manually effect (side to side). That would indicate the wheel bearing assembly needs to be replaced.

My question is why do you let the engine start "jumping" before you downshift? I suggest downshifting before the engine starts straining. If you don't get wobble, problem solved.

On a side note: Did you go to highschool with me and take drivers ed together?
Me and another guy in backseat of drivers ed car. Teacher in front with girl driving, manual transmission car. Teacher tells girl to pull over to change drivers. She pulls over and starts to slow down. As she slowed down the car started lurching until it stalled. The teacher calmly said to her, "Next time put the clutch in before you stop."

I agree, I don't purposely strain the engine but I am still learning to drive a stick shift so it happens sometimes.

Also do you have to or is it good to heat up the engine before you start driving ?

I don't do it on my honda civic but I do it on my sport bike.. I am not sure about jeeps.

I would just check to make sure everything is tight and there is no play. Take a special look at control arms and your track bar.

As far as learning stick...if you are coming to a stop, rather than downshifting and lightly using the brakes, try putting the jeep into neutral and use your brakes to stop you. Nothing says you have to down shift to slow down.

20-30 seconds max is as long as I'd wait before driving if the morning was exceptionally cold. You certainly don't have to let it warm up before driving.

Yup, thats how I do it now, after some experience. I put it in neutral if a stop sign or red light is ahead.

When starting, especially cold, I wait until oil pressure is up before moving. It's also a good idea not to be romping on it until the engine is heated up and oil has thinned out.

I know on high performance cars it is common practice to wait until the engine is fully warmed before going for a... "spirited" drive.

Looks like the wobble is fixed, the track bar bolt that connects to the body was little loose . Tightened it and now the jeep hops like a squirrel

Make sure you keep an eye on that bracket. It may be wallowed out now.

so if it is wallowed out then the solution to that would be a bigger diameter bolt ?

Sometimes a larger diameter bolt can be the fix. Other times, not everything associated with the wallowed out bolt hole can accept a larger diameter bolt. In those cases, it normally takes welding another piece of steel over the part with the wallowed out bolt hole with a new correct diameter bolt hole drilled into it. That is easily done by any competent welder, I have had to do that a couple times on my TJ.
