The stock E36 lower u joint uses a rubber coupling (giubo) that cracks over time and causes sloppy steering. This upgraded lower u joint is from an E34 model and eliminates the rubber coupling all together. By doing this you can expect a more direct feel, and tighter steering. This is a must have modification on all old E36s. This U Joint will is also a direct replacement for E34 steering shafts (BMW PN 32311151454) Don't be fooled by the cheap ~$50 Amazon/Ebay knock offs. They are too short to work for this modification and will not work. Special Installation Note: Since the E36 did not have a provision on the lower part of the shaft for a pinch bolt, you will need to drill one to make this u joint work. Don't fret, this not a hard task. Simply install the u joint onto the e36 shaft and take a drill that same size as the bolt hole and drill through the aluminum shaft. Keep in mind this does not ruin your E36 steering shaft. If you ever wanted to go back to the stock application, it would all still work.

We created an exact replica over 50% off the original price. NOTE: Will not fit Z3 model cars. NOTE: Will still work with Z3/E46 steering rack swaps. 32311151454
