Suspension / DF Gurus chime in please.
My xB2 is lowered on DF210 and I don't know when it started but the driver's front has a "KINK" sound coming from it depending on the bumps on the roads. "KINK" is the only way I can explain it but I think there's some metal to metal rubbing when I'm hitting the bumps on the road. It almost sounds like it's getting louder and louder by the day & I've only hit 5700 miles on the bad boy.
Without taking it apart yet, is this a common problem and what might it be?
Thanks for input.

According to the front strut remove/install info from Scion:
As I recall..... the nut on the top of the strut (under the dust cover) is not supposed be to reused again. It calls out for a new nut to be installed. I would think that some BLUE Locktite would do the job OK also.
Good luck.

You do what you want, but that nut is NOT DESIGNED to be backed off and then tightened down a second time. And give me a break about the price... it's 2 nuts that are $2.46 each. We're talking about suspension lock nuts, not some trivial nut that just holds a hose or wiring against a body panel.
To answer your question: No, I don't think everyone that owns a scion and lowers it replaces those nuts (not bolts) with brand new ones. I do think it's ignorant not to replace the lock nuts with new ones. Notice I did not use the word stupid, because I believe the majority of people who don't replace these nuts truly don't understand the importance of their design and what they do.

Lock nuts differ from standard nuts in that they have pitted grooves built into them that are designed to interlock with protruding pieces in locking surfaces to create a more secure fastening hold and prevent fastener slippage.
The lock nut has a steel exterior with a hard formed nylon interior. When the nut is threaded onto the strut bolt, the nylon is compressed and binds onto the threads of the strut bolt. The nylon literally binds itself onto the microscopic imperfections of the bolt. This keeps it locked on throughout the excessive stress and vibration that the suspension transmits to the top of the strut. It is also resistant to rust and corrosion, which could cause a catastrophic failure of the front strut, and potentially result in an accident.
When this lock nut is removed, small amounts of the nylon that was bound to the steel strut bolt is shredded away. This means that if this nut is ever reused, it will not have the same amount of nylon thickness and threads to properly bind to the strut bolt, as it was designed to. Using a new lock nut each time ensures that the maximum strength is achieved for the proper fastening of the lock nut to the strut bolt.
This is why Toyota is so expressive in their instructions that they not only specify the lock nuts by part #, they also put the word "new" in bold print; "Install new shock absorber nut." I invite you to take a look at page 5 of their spring installation instructions: http://www.trdsparks.com/install/PTR07-52080inst.pdf
I hope this clears it up for everybody, and impresses upon you how important it is NOT to reuse these little $2.46 nuts.

Actually the moral of the story is: if you want to be safe and do the job right, get a new pair of nuts.
Like I said earlier... Do what you want.
At least now people will understand that there is a safety and engineering purpose for the specification of using new locking nuts; so SupaGlove, thanks for asking.

*raises hand* I reused my nuts. I'm ignorant. No lie. I installed everything at around 9pm. Dealer was closed and I didn't want to wait until morning. Meh. It works. But I'm sure I'd be better off if I had purchased new nuts. Chances are my dealers don't have any... *rolls eyes*
Anyway, I had a weird noise after I installed everything. Granted, I don't have DF's, but I HAVE installed DF's. I'd recommend checking the endlinks that bolt on to the strut from the sway bar. That's where mine was making a noise.

BTW, most dealerships keep these nuts in stock all the time, because they use them when people buy the TRD springs.
And thanks for being big enough to admit you're ignorant; let me know anytime I can be of help with that.

Probably a stupid way of doing it but I yanked out the wiper blade motor and shafts above the struts today and tried to impact the strut nut from the top side. It didn't budge at all or very little so to speak. Took it around the neighborhood and the noise went away until about half way through the drive and the noise returned.
Thanks sir I'll have to check the end links tomorrow morning then since I took it off.
