Speed bump clunk

Still don't get ever it tops out so violently. Why is there no rebound dampening?

And it's not just speed bumps its also on speed "humps"....the longer, raised kind that they put in residential areas to keep people under 25mph. I can't even hit those at more than 15 or the loud clunk happens. I have never slowed down on those and now with my "upgraded" suspension I have to crawl over them? So disappointed with this suspension. How is everyone else dealing with this? My truck cant be that unique and I know others have more lift than mine.

 

I have the same issue with my TRD pro suspension on an 08 2.7 4x4 5 Speed ... I’m at 22.5” of loft (hub to fender) ... I am moving to AZ, but need to measure out droop and see what going on ... may just need some new UCAs :-/

 

Put some limit straps on the front. See my avatar....

They limit my down travel by about 1/2". Got rid of my clunk and not too expensive.

 

Only thing with limit straps is you’d essentially bounce over a speed bump instead of the suspension doing its job.

The best thing is to find the limiting factor, prolly the UCA, and correct it.

It’s sad the TRD Pro suspension acts this way, too much lift for the shock travel. Too little droop. I’m disappointed in that regard. Someday when the bank account says “full” I’ll take the plunge on some UCAs

 

check your lca cam tabs, if they are flared out they will cause play and metal clunks

 

Mine did this to when I got my ome lift. The I got my ARB bumper and winch...never happens now unless I get airtime.

 

Mine literally limit the full droop by about 1/2" They don't feel like they limit my travel at all, just avoid the clunk at the bottom.
We have a small bridge near us that I catch air on, on a regular basis. Everything is working fine. When I bend a spindle, I'll buy new ones and weld on some spindle gussets.

 

yall are looking way to into this.

Doesnt matter the lift, unless you are running limiting straps your shocks are limiting suspension down travel. Stock UCA's ball joints actually have right around the same or greater range of motion than aftermarket uniball suspension, but clearances between the inner part of the UCA and coil get tight with the extra droop of the 5100 front shocks.

OP is the clunk in the front or the rear? Id bet the rear.

5100s that are meant for the rear of our tacomas are no longer than stock shocks thus offer no extra droop travel.

 

I agree, its the shock travel limiting droop on these trucks and not the uca. Wish I had it apart so I could cycle the suspension and see for sure, but I'm pretty sure you are right.
Its definitely the front and not the rear. You can identify the clunk long before the rear end goes over the speed hump/bump.

 

I'm experiencing the same issue, but with Kings. No sway bar, no coil-UCA touch.

I recently started hearing my lower ball joint squealing so i'm about to tear it all apart and do bushings and ball joints. Hopefully that takes care of the clunk.

I have inner and outer tie-rods as well, but wanna see if the LCA consumables are the issue first.

 

Stock uca?

 

Total Chaos with Uniballs replaced about this time last year. That's not out of the question though... Issue started after i got the Kings on, last month. Going from plush rubber upper and lower mounts on my 5100's to stiff heims on the Kings, leads me to the LCA/ball joint.

 

Makes sense.
I just don't get why the 5100s have such weak rebound dampening. It' only a 600lb coil.

 

Be careful, its possible you are topping out on the UCA's uniball which will end up snapping the bolt that holds the UCA to the spindle... thats no bueno.

 

That was almost the case with the 5100's. Kings are shorter, so no chance there.

 

Not sure if you figured this out, but my issue was because the Kings were too short. I added a 1/2" top plate spacer and readjusted the coils. Like a new truck.

 

I'm pretty sure its the same issue for me-5100 just not enough down travel. I'm just living with it at this point. I wonder how people with the full 3" lift deal with it and don't mind.
