Fixed my '88 hatch pulldown...

Got my hatch pulldown working again...turned out the guides had turned into hundreds of small nylon chunks, Top Down Specialties had the replacement guides for $25.00.

The gear itself was completely stripped where it runs on the worm gear from the motor. Pulled a trunk pulldown from a Cadillac DeVille, from a junkyard, which has the identical motor and gear. Took the DeVille mechanism apart, swapped the parts in my pulldown, and replaced the guides.

Took about an hour and a half, and the cost was less than $40.00 for the new guides, and the junkyard motor/gear. Works like new again!

It really sucks when those 'guides' start to wear out,....... when they get really worn/busted-up the it causes the hatch pull-down assembly to rattle like crazy !!

I remember that some Caddys' used the same gear; do you know what years were compatible ??

I'm pretty certain I got mine from a '96 DeVille.

I'm glad the TDS 101170 aftermarket guides solved your problem.
