Step-by-Step Guide: How to Shorten Rear Axle Housing
Now that you have your tools ready, follow these step-by-step instructions to shorten the rear axle housing:
Step 1: Measure and Mark
Using the measuring tape or ruler, measure and mark the desired length of the axle housing to be shortened.
Step 2: Remove Axle Shaft
Raise the rear of your vehicle using the hydraulic jack and support it securely on jack stands. Then, remove the wheel from the side of the axle housing that you will be shortening. Afterward, carefully remove the axle shaft from the housing.
Step 3: Cutting the Axle Housing
Using the angle grinder or cutting torch, cut through the axle housing at the marked point. Take your time and ensure a precise and straight cut.
Step 4: Align the Ends
With the axle housing cut, place the two ends together and align them perfectly. This is crucial for maintaining the proper spacing and alignment of the rear wheels.
Step 5: Weld the Ends
Using your welder, tack weld the ends together. Double-check the alignment and then proceed to weld the ends firmly.
Step 6: Clean and Smooth Weld
Clean the welded area using a metal file, removing any excess or unwanted material. This will help create a smoother finish.
Step 7: Reinstall Axle Shaft
Reinstall the axle shaft into the shortened rear axle housing, ensuring it fits properly.
Step 8: Reinstall Wheel and Lower the Vehicle
After successfully shortening the rear axle housing, reattach the wheel and carefully lower your vehicle using the hydraulic jack.
Step 9: Test Drive and Alignment
Take your vehicle for a test drive to ensure everything feels right. If you are experiencing any issues or misalignment, consult a professional for further adjustments.
