I been having ongoing issues with the rear differential in my vehicle – it keeps breaking, and I'm at a loss for what to do next. Every time I think I've got it fixed, it ends up failing again. I've already tried replacing the differential multiple times, but it seems like no matter what I do, it keeps breaking under normal driving conditions. I suspect there might be some underlying issues or weaknesses that I'm missing. Does anyone have any suggestions on how I can strengthen the rear differential to prevent it from breaking in the future? Are there any specific upgrades or modifications I should consider?
