Rumbly Suspension Query (drop link help needed!)

Hi, just wondering if anyone has any tips.

Problem is, car suspension feels rumbly through the front when going over small bumps and very noticeable over uneven roads/concrete.

I've Mr Zetas coilovers on new from last year, so it shouldn't be them, just wondering if it could be more an issue with track rods, ball joints or even wishbone bushings?

Tracks and balls been changed several times over the years, just not had a chance to check these all again.

Thanks

Stu

could well be the bottom balljoints. also check the droplinks, track rod ends and the track rods themselves.

check your engine mounts are in good condition and not metal to metal somewhere. also check over your coilovers to make sure everything is tight.

something i have had issues with myself is the steering column. it can get a bit rattly when they get a few miles on them, they can then rattle when you hit certain bumps, uneven ground. to test this try going over the bumps, uneven surfaces that cause you issues, push your foot upwards to put pressure on the steering column and see if this stops the rattle.

Yeah i'll check over all of them, as its starting to grate on me :)

The droplinks and front ARB bushes are TRD, but changed them a good 4 years ago I think.

i wouldnt rule out the droplinks. the arb bushes will likely be ok at only 4 years old though.

give eventhing a good check over. it can be frustrating and sometimes you have to wait for it to get worse before you can actually locate it!

I'm just wondering if I need to start replacing them all to refresh it, MOT coming up in Oct as well.

I've never changed the bushes in the wishbones, so they will be 18 years old or so, you ever changed these?

I'm going to go over it all this week, hungover today so couldnt face it!

you can either change stuff and hope for the best or just see what the MOT throws up. you can go a month before hand without loosing out, so if it fails you have a month to sort any issues.

i have never changed the bushes on the arms. never had the need too. never even had to change a bottom balljoint yet ;)

If I were you would rather replace the suspension up front and see if it sorts out your problem and yes the coilovers can be a pain in the ass on uneven roads or small bumps - there were not designed for it. The label clearly says FOR OFF ROAD/TRACK USE ONLY.

Hi, it looks like my drop links are very tired.

I ordered new ones there from camskill, however before I have to saw off the old ones (bottom nut totally buffed), the new ones have 14 mm thread on both the top and bottom, so the bolt is thicker on the down piece (the stock one is 12 mm at bottom, and 14 mm at the top of the joint).

Will the new ones fit, or is the hole in the wishbone only sized for 12mm?

Cheers

Stu

They will fit fine mate.

If you are talking about the ball joint bit, they normally seize solid and need cutting off

the lower arm hole is 18mm so you have plenty of room. Yes an allen key goes into the end of the drop link to stop the link turning, aftermarket ones just have a lock nut.. I replaced the stock toyota bushes with some whiteline polybushes and this help get ride of the noise for a while. I think Trd did some uprates droplink bushes also.
