I use a GT LTS Team to commute to work. Well every
other day the rear suspension sounds like your having sex on an old
steel spring bed. You with me still. Did lube did work for 2 days. Then
I took it all apart and greased it sounds were back in a few days. Its
been a humid summer so far. So now I come up with this fix. I heavy
spray with Liquid Wrench, follow with WD 40,and finish up with STP
Silicone Lube. Not a sound in 5 days and its been humid.
