Need to know how to tighten a loose wheel after a brake job was done on my 2002 trooper (left front 4 wheel drive)

Have you recently changed rotors?

Symptom: Brake Pedal Pulsates Change When: Braking Change Where: Passenger Compartment Change -->
Priority Action Part Type Cause 1 Inspect Brake Drum Specs Brake Drum Out of Adjustment, Out of Round, or Cracked. 2 Inspect Brake Drum Unevenly Worn or Out of Round Brake Drum(s). 3 Inspect Brake Rotor Incorrectly Machined Brake Rotor. 4 Inspect Wheel Bearing-Front Incorrectly Tightened or Installed Wheel Bearing. 5 Inspect Wheel Bearing-Rear Incorrectly Tightened or Installed Wheel Bearing. 6 Inspect Wheel Nut Loose, Worn, or Damaged Wheel Nut(s). 7 Inspect Rear Axle Bent Rear Axle.

CV joints OK?

two things, re check job done on front brakes mybe improper fittings on pads and sensor,next is check rear brake pads and sensor condition, mybe need to replace too...

ok, there are 16 pins in the DLC you want to jump #4 and #12 as you look at the connector from left to right top row is 1-8 bottom row from left to right 9-16, both rows the 4th pin jump them together. then count the flashes all codes are 2 diget ( example flash-flash pause flash-flash = code 22 )

Tools:
1. Combination Wrench Set
2. 3/8 in. Drive Ratchet
3. Floor Jack
4. Jack Stand Set
5. C-Clamp
6. Mallet Hammer
7. Flat Head Screwdriver
8. Socket Set
9. Tire Iron
10. 1/4 in. Drive Torque Wrench

Supplies:
1. Brake Cleaner

Steps:
Step 1 Park your vehicle on a solid level surface. Set the parking brake and chock the rear wheels.
o Tip: Safety Tip:Always wear safety glasses when working on your vehicle. Wear other personal protective equipment (PPE) when necessary, for example latex gloves or safety shoes.

Step 2 Remove the front wheel hub caps if applicable. Using a tire iron, break loose the front wheel lug nuts but do not remove.
o Tip: Lug nuts fasten the wheel to the hub and may be on very tight. To gain more leverage, use a breaker bar to loosen the nuts.

Step 3 Using a floor jack, lift up the front of your vehicle.
o Tip: Using an aftermarket floor jack, instead of the original equipment (OE) jack, can make the job easier and safer. Verify the condition of the floor jack before use.

Step 4 Secure the vehicle with jack stands on both sides for safety before starting any work. The pinch welds or the frame rails are the two best locations. Do not rely on the jack to hold the vehicle up while working.
o Tip: Try to find a flat, level, and strong surface to put the jack stands.

Step 5 Remove the front wheel lug nuts. Remove the front wheels and set them aside.

Step 6 Inspect the brake caliper for any signs of binding. Look for rust and uneven brake pad wear.

Step 7 Remove the brake caliper mounting bolts (sliding bolts).

Step 8 Support the caliper up and away from the working area. Make sure you do not kink or pinch any brake lines.
o Tip: Use a bungee cord to secure the brake caliper out of the way and hang it on the suspension spring.

Step 9 Clean the sliding bolts and lubricate them.

Step 10 Install the new caliper over the brake pads and rotor. Attach the caliper to the mounting bracket with the sliding bolts. Tighten the caliper sliding bolts to manufacturer’s specifications.

Step 11 Disconnect the brake line from the old caliper. Attach the brake line to the new caliper using new copper washers. Tighten the banjo bolt.

Step 12 Repeat for the other side. Bleed the front brakes.

Step 13 Reinstall the front wheels. Torque the lug nuts to the manufacturer specifications in a star pattern.

Step 14 Remove jack stands and lower the vehicle to the ground.

Step 15 Verify that you have a solid brake pedal. Road test the vehicle to verify brake caliper repair.

Hope this help (remember rated this).

you need to provide more info on engine size 2 or 4 wheel drive to locate part for you to give time frame for difficulty and need to know how to test system in order to find is working properly accorking to labor hour is going to be less then an hour on the limited edition.

the wobble you referred to many be the front wheel bearings.
jack the front end of the astro up and wiggle the front tires.

if they wobble or there is a lot of movement check the front
wheel bearings on both sides. they are inexpensive.

Could be cv axles need to be replaced, to have them done usually around $100 - $150 each side.

This could be several things. How are the brakes right now? I'm wondering if something wasn't tightened properly when you had work done on the car recently. You need to jack up the car and grab hold of the wheel and see if there is any play (looseness) when moved from top to bottom in and out, and front and back in and out. It could be a wheel bearing or cv joint, although with 52k it shouldn't be a problem. Pull the wheel to visually check for something obvious. Caliper secured properly, brake pads ok, etc. Some brake component may not have been properly tightened. Let me know what you find. Good luck.
