New ATS Diff and Replacing a Bad Knuckle

Last year we identified additional items that needed to be replaced over the winter. The ATS diff that I had been running for the past 3 years was still working but the clutch packs were starting to slip. Rather than have it rebuilt, I opted to send Lupa's spare OEM diff housing over to Karcepts and have Brian install the new ATS Spec III Type DD LSD in it. Since we had a break in the weather this weekend, SJF Performance installed the replacement pumpkin as well as replaced the passenger side axle with the matching spare to the driver side axle that broke during Nationals as a precaution. We also noticed that one of my rear diff mounts was installed backwards so we corrected that as well.

When SJF was installing the new camber joints last year, he found that the threads on the passenger side front knuckle were cross threaded from a previous installation. He was able to tap and fix the threads but we weren't super happy leaving it that way. I picked up a used AP1 passenger side knuckle and he replaced the wheel bearing and hub and installed a fresh set of ARP extended studs so I could keep the old knuckle as spare complete unit.

This completes all the major mechanical work that needed to be done over the winter. She only needs an alignment and new fluids before the season starts.
