I noticed a small amount of fluid pooled underneath a 97 Big Bear.

The rubber boot that covers the rear arm to what looks like the transmission has pulled away (clamp came off) and there is oil very slowly dripping out.

See Pic,

After researching on this forum it seems it is either the rear seal needs replaced or the rear yoke nut needs tightening.

Can someone confirm I am on the right path?

Thanks,
