I had the Toytech spacer lift and SPC UCA installed roughly 600 miles ago. Lately I have been getting a thump in my steering wheel.

Feels like something is loose in the suspension. Like a sway bar rattling. BUT I can only feel it.

Everything is tight, truck tracks straight, no audible rattles over bumps. I’ve jacked up the front end and tried to shake the wheel left/right, up/down to check the balljoint. Everything felt tight. It is a intermittent issue.

I check/retorqued all bolts. Checked that the ballpoints were greased.

On a side note, I traced down a squeak to the hood latch. And it appeared the rubber stoppers were set all the way down. I adjusted them up Alf a turn and oiled the latch then went for a test drive. I didn’t notice anything. I didn’t feel the “loose” feeling.

Could it really be the hood rattling in latch????

Update, some people told me to check the sway bar and it sometimes contacts the shock/spring/rad support.

I took some photos. It seems to be pretty far from the radiator support but less than 1/2” from the shock.

i got a 15' BroPro , i got the same steering clunk feel over light bumps, potholes, though it was steering rack, tighten and re-torque still clunk, funny thing is when i go hard on the suspension past week in anza no clunk.. buddy just picked up a 18' pro gotta find a road to recreate clunk and do it with both, see my findings.

I'm not saying this is your solution but its a direction to look.

Tsb: some 2015 - 2016 model year trd pro edition 4runners may exhibit an abnormal clunk type noise when driving at low speeds over certain road surfaces. the condition may also be more evident in colder climates. the trd pro shock absorber

I took the skid of tonight and looked at the rad support brackets. Check out the rub mark on the driver side bracket! It must be almost riding in that thing :o

I made some square rubber washers to sandwich in between the rad support and the body in hopes to dampen the noise and feeling.

I’ll be ordering a sway bar relocation kit.

I kind of think there might be a market for custom designed brackets that allow clearance for the swaybar and still let you use the Pro skid plate??? CBI, RCI, SSOR, C4????
