Greetings,

I was driving the 97 T-100 around in the snow on the roads and discovered that it is popping out of 4 hi. It doesn't forcefully pop out and it'll stay in if someone just gently holds it in place.

I drove on a dirt road in 4 hi recently and didn't have the problem but I wasn't going very fast, < 20. Now on the highway, it was frequently going out of 4wd, around every couple minutes or so.

Any thoughts on the cause and cure? Broken spring on a detent ball perhaps or something more drastic?

Thanks in advance.

Chip
