noisy electric window - why?

[psyolent]

so i replaced my elec window in my vt with another one - of unknown origin. the one in there was stuffed.
its really noisy and makes a horrible groaning noise - sure operates fine, certainly motors up and down no problems, just noisy as hell?
our VX's are not like this at all.
is it a cheap shitty aftermarket motor thats the problem or something else?
i didn't use the rivets, but instead used bolts to hold the reg in place - its secure and no issues / tight.

any thoughts? i'm guessing cheap shitty aftermarket reg....

no grease in the gearing or cable on the mechanism? sorry cant remember what vt's have

thats cool. ta. theres no cable, theres a gear and teeth that moves through, which, is plenty greased. the old motor did this, so i swapped it. so this one does the same. so not sure if its the motor.

What about dry window runner rubbers? Try silicone spray, should be applied regularly.

wouldn't have thought that would have been in G, as the things are bloody quick / hammer up and down no probs. but worth a crack aye
