LCA hitting ball joint

I hate to tell you it is the 882s I had him on my 04 for a while and I didn't like them I thought they were just too tall of a coil your maxed out. When drooping aka tires go down you're hitting that upper bump stop. Maybe try putting some white paint on the upper bumpstop and seeing if it transfers. I believe it hits on the upper control arm I bet if you look at it at ride-hite it's really close I had this exact same thing on my 04

 

Hmm... alright. I haven't read of any issues with people using OME 882 coils and 5100's together. Then again, I don't know how many of those people actually wheel their trucks.

 

Now, if I went with light racing UCA's... I should be fine correct?

 

I don't think ur hitting the uca.
I think u are hitting the rubber bumpstop so it's just a noise not gonna hurt anything.

 

Gonna look something like this just keeps ur suspension from going down any further. Now that ur running a super tall coil that has ur uca close to it at ride hite.

 

Alright, what's the fix?

 

Well if you're prerunner they make lo profile bumpstops.
If ur 4x4 I don't think I'd run them as I think that's the last little bit that would allow the cv and break. I've read.
So it may just be life on 882s.
After the new springs settle there may be enough room it won't happen as often.
1st I'd confirm that is indeed ur noise.

 

Typically people just live with it...youre certainly not within a small group of people that experience this very same thing everyday they drive....

 

i think you hearing what i have. the upper control arm is pivoting so low it twangs into the spring, then plucks it on the way back out when the truck lowers.

2 things you can do to recreate the issue.

1) disconnect the sway bar on the side you want to inspect and lift your truck up til the tire raises from the ground. it should reproduce the issue.

2) know anyone with a lift? have them just raise your truck til the tire is off the ground and set it back down. you should be able to reproduce the issue that way too.

or 3) if you have a better idea that would cause the same effect, do it!

it's all about figuring out what is going on.

 

Im sure that is his noise...that and or the control arm possibly plucking a coil ever so slightly as just previously mentioned. Regardless it is definitely just a simple case of the suspension at its limits in the current configuration. Again OP nothing to be concerned about as far as creating issues down the road....



Question for you @Catcrazed ...both my tacomas and my runner dont have any upper bumps like you posted in that pic. I also have never heard or seen them before. Is it a peerunner thing or perhaps they only came on later year model trucks? Just curious....

Anybody else have any insight on the whys and why nots as far as the upper bumps are concerned? Catcrazed dont wanna unleash his knowledge onto me, i think he figures it'll be too much for me to handle....lol..J/K!

 

I'll have to rule this out, as when I did the lift last week at the shop with a lift, I visually inspected everything at full droop for rubbing or contact. I guess I didn't inspect that. Its a prerunner so I shouldn't have an issue putting smaller bump stops right?

 

I will confirm this tomorrow when I get it up on a jack. Being a prerunner, they should damage anything correct?

 

Cant be fur certain but id bet the issue isnt the arm plucking a coil but rather just the suspension comming to its limits. You hear it as well as feel it when it occurs correct? If it were a coil being plucked there wouldnt be much of a "feel" to it...just guessing here however, both are realistic issues to have occur...

 

no, it's not the control arms being maxed out. I'm talking about the bushings(from the frame to the control arms).

The stock bushings are rubber and can only flex a certain amount. When you lift it, you push the control arm down farther than it would have normally traveled at stock height. The bushings are essentially "fixed" (press fit) into the control arms, and there's an inner metal sleeve that is held tight against the frame when you tighten the main pivot bolt.

The clunk you hear *could* be the inner metal sleeve shifting back and forth.

 

Ah, I understand... and is there is an actual fix for this?

 

if that is indeed the problem, you could jack the truck up and loosen the pivot bolts and knock it around a bit or cycle the suspension, then re-tighten them.

Or urethane bushings...

 

This'll be step two, first I'll try smaller bump stops. Of which first I need to find online. Can't tell what's shorter and what isn't.

 

Ya know I pulled that pick off Google so not 100% if that's a taco picture.
And it been like 4 years since I got rid of my taco. But I'm pretty sure my 04 had tops and bottoms.
Do some looking around I'm sure there something

 

If the UCA is your problem, the easiest way to tell is to just jack the truck up (by the frame) so your suspension will be at full droop and take the tires off so you can see easier. Then check clearances of everything like the spring, bump stops, UCA, etc...

 

Actually, my 04 doesn't have top-out bump stops, only compression stops.
