Which axle do I have?

[Romer]

I need new ball joints (upper and lower) for my '92 Ford Explorer and I'm going to do them myself. I just need to know which axle I have. They have ball joints for either Dana 28 or 35. Is there anything to identify the axle?

Thanks.

'91-'94 Explorers came with the D35

The D28 is a BII unit
