Solution

1. Preparation

Gather tools and parts before starting the repair.
Ensure the vehicle is parked on a flat surface with the engine off.
Disconnect the battery to ensure safety during the repair process.

2. Inspect and Repair Brake Components

Sub-steps:
1. Remove the wheel to access the brake caliper.
2. Inspect the brake pads for wear and the caliper for sticking.
3. If the caliper is sticking, remove it by unscrewing the mounting bolts.
4. Clean the caliper guide pins and lubricate with brake grease.
5. Reinstall the caliper and wheel, then torque the wheel bolts to manufacturer specifications.

3. Examine Drivetrain for Binding

Sub-steps:
1. Raise the vehicle securely on jack stands to access the drivetrain.
2. Visually inspect the driveshaft and axles for any signs of wear or damage.
3. Rotate the driveshaft by hand to check for binding or abnormal resistance.
4. If binding is found, replace the damaged driveshaft or CV joints as necessary.

4. Check and Replace Transmission Fluid (if needed)

Sub-steps:
1. Locate the transmission fluid dipstick or fill port.
2. Remove the dipstick and check the fluid level; add fluid if low.
3. If fluid is dirty or has a burnt smell, drain the transmission fluid.
4. Replace with manufacturer-recommended transmission fluid.
5. Recheck the fluid level after replacing.
