11 Step-by-step Guides on How to Properly Align Leaf Spring
Step 1: Measuring Axial Misalignment
The first step is to measure the axial misalignment between the frame and axle. This refers to the distance between reference points on both parts. Use a measuring tape or string to determine this measurement. You can measure at multiple points to ensure accuracy.
The ideal alignment is when the distance on both sides of the vehicle is equal. It is normal for there to be a slight difference, but anything more than ¼ inch needs to be corrected. You can do this by adjusting the alignment of individual leaves using a pry bar or hammer.
Step 2: Adjusting U-Bolts and Leaf Spring Mounts
If the axial misalignment is within acceptable limits, you can move on to adjusting the leaf spring mounting bolts and u-bolts. These should be tightened or loosened in small increments until they are snug but not completely tight. This will allow for minor adjustments during alignment.
You can also use a pry bar or hammer to adjust the alignment of individual leaves at this stage if necessary. But be careful not to over-tighten and damage the bolts or leaves. The aim is to achieve equal distance on both sides of the vehicle.
Step 3: Transverse Misalignment Corrections
In this step, you will address any transverse misalignment between the left and right leaf springs. This refers to the tilt of the leaves in relation to each other. Use a jack to lift one side of the vehicle at a time and adjust the alignment using a pry bar or hammer.
Once again, be careful not to over-tighten and damage the bolts or leaves. You can also use shims to adjust the alignment if necessary. It is essential to check and adjust the transverse alignment at multiple points along the length of the leaf springs.
Step 4: Using a String Method for Alignment
An alternative method to using a measuring tape is the string method. This involves tying a piece of string between two points on the frame and axle and comparing the distance between the string and leaf springs on both sides. The ideal alignment is when this distance is equal, but you can make small adjustments with shims or by adjusting individual leaves if necessary.
Although it may be slightly more time-consuming, the string method can provide greater accuracy in alignment. You can also use a laser alignment system for even more precise results.
Step 5: Checking and Adjusting Leaf Spring Arches
The arch of your leaf springs can also affect alignment. If the arch is too high or low, it can lead to misalignment and other issues such as a harsh ride or bottoming out. Check the arch of your leaf springs against the specifications provided by the manufacturer and make any necessary adjustments using shims or a pry bar.
There should be an equal arch on both sides of the vehicle. If not, you may need to replace the leaf springs. You can also use a leaf spring spreader tool to adjust the arch if necessary.
Step 6: Alignment Verification through Test Drive
Once you have completed the alignment process, it is crucial to take your vehicle for a test drive to ensure everything feels stable and aligned. Pay attention to any pulling or drifting and make adjustments if necessary.
It may also be beneficial to recheck the distance between reference points on the frame and axle after the test drive to ensure they are still within acceptable limits. The test drive should also be used to confirm that the vehicle’s handling and stability have improved. It is recommended to take your vehicle for a professional alignment after making any adjustments.
