1990 Jeep Laredo front end shakes

Check the front rotors they may be warped, Declan.

Unless you pay on here you will not get any advice and the advice on here is below average when it comes to Jeeps.

What you need to check are not your brake rotors. This is a typical problem for Cherokees and Wranglers. You need to check for any loose or worn parts in your steering such as tie rods, bearings, all bushings especially your control arm bushings. Any loose or worn parts cause the "death wobble" in the front end of these jeeps and it will seem like the whole front end will fall off at any second. Also, if your steering dampener is leaking and you have worn parts...it will amplify the problem.

My experience was when I braked at around 50mph I got the death wobble, I had put on Chinese rotars and when I turned the origonal rotars and put them back on I solved the problem, its just my opionion, ciao Declan.

If people are going to reply, please take the time to read the question completly as he did not mention pressing the brakes to get a shake.

You are correct, Declan.

beef is quite right. you need to check the bearings and steering. also. something he didnt mention but can come into affect is your tire balance. however, since it didnt do the wobble before the lift then it is most likely not the cause but it could be part of it
