My jeep front end shacks , i have replaced all worn parts and aligned.

Hi Eric, it sound to me like the modulator in the trans is faulty. This modulator is what controls the shifting in the trans.It details a 30 minmute repair by your transmission specialist. The replacement part should be around a hundred dls, plus the labor. While you are at it, have the filter changed in the trans for carefree shifting.

Many things will cause vibrations, especially on 4WD trucks. Causes include: worn ball joints, worn tie rod ends, bent wheels, tires out of balance/shifted belt in tire, worn steering dampener, worn u-joints, worn CV joints, engine problems such as engine misfire, a bad fuel injector clogged fuel filter or injectors, worn ignition parts, etc. I suggest you apply the service brake in gear and give it a lot of throttle (power-brake)to determine if the engine is running smoothly or if it runs rough. Also, with the hood up, you can see the shaking if it occurs. If rough, check everything over and repair as necessary. If smooth, start checking ALL other vehicle systems and repair as necessary.

There are a few things that could make this happen, it could be that you have a tire that is out of round, that the front end is out of alignment, that you have a bent wheel, or that you have a bad/weak strut/shock. When the tires were balanced the technician should have been able to see if the tire was out of round, or that the wheel was bent, but remember that SHOULD happens and he may not have known to look for those issues. I would recommend that you have the alignment checked out, it is free at most places, and they can give you a better more precise answer to your issue, seeing as they will be able to inspect all of the suspect parts.

The drive shaft universal joints or joint is worn it must be replaced. This should cost under $200.00

sounds like it time to have the front end balljoints inspected. Only with an inspection will you get the proper results. Why guess, this is a safety issue.

yes they should

I had the same problem and it was a small shock sitting horizontally called the steering stabalizer your something close to that. Eazy fix.

call jeep and give them last 9 digits of your vin and ask for three things -Differential Type,Gear ratio, and Track lock- They will give you
1) Dana 35 or 44
2) Gear Ratio 3.31 or 3.73
3) Track Lock - yes/no

1994 is the same as 1997. parts are interchangeable

no it wont work.they made too many changes with them about 2 years older and id say yes but no they wont interchange
