So I had a little bit of a problem today. I was on my way to work, cruising at a mild 40mph and the car decided to lock up the rear wheels and skid for a good while. Thank god I held it straight and prevented it from going into the curb. Initially I’m a little shocked as I sit still in the middle of traffic, but then I try to continue driving as if nothing happened. The only issue is; the car didn’t move. I instantly knew it was most likely the diff, as I had welded it a week ago. I had solid welds on the spider gears, along with welding in plates just to make sure if any of the welds did snap that it would still stay out of the ring and pinion gears. I checked to make sure the driveshaft was still connected to the diff and it was, so I have no clue as to why the axles won’t move. My buddy towed me to work which luckily was only half a mile away, and I’ll most likely be dropping and opening up the diff tonight to see what happened. Before I do though, I just wanted to see if anyone knows what the cause of this issue is. If anyone has an answer, thanks in advance for letting me know.

 

Wow this is scary, I have never heard of this happening. Keep us posted on what you find out when you inspect the diff.

 

Yeah no kidding, I was really shocked when it happened, but was even more shocked when I couldn’t find anywhere that this had happened to someone else. I’ll be dropping the diff after school to see what went wrong, and I’ll make sure to keep you guys updated.

 

Disconnect the differential from the driveshaft and axles... More than likely something came loose in your diff, jammed things up, and caused it to seize. The reason I say to disconnect and check is that there is a possibility you had a wheel bearing fail and lock up, which with the diff welded will cause both wheels to lock. Take a look and let us know!
