Front suspension clunk - front passenger side

Postby brickbox » Sat Jan 25, 2020 11:10 am

I’ve been noticing a clunking sound coming from the front passenger side when I drive over bumps. Crawled underneath and found that the outer tie rod (which is a moog problem solver replaced by the PO at an unknown mileage) is wet - see picture.

In addition, there’s an additional mount on the top near the coil spring that is wet as well. However, this mount is wet on the drivers side as well.

1. Can the tie rod be clinking? I tried to wiggle it around with the car jacked up I couldn’t do it. Interestingly, I can rotate it but it takes more effort compared to the inner tie rod on the driver’s side.
2. What is the bushing/mount on top of the suspension? Can it be that this is the one that is clunking? If so, does it mean that the one on the driver’s side is also on its way out?

With the front wheel jacked up, grab it at 3 and 9 o'clock and try to wiggle. If it clicks or moves its probably tie rods. Grab at 6 and 12, if there's clicking there it's a ball joint (the thing at the top or bottom that you circled and asked about).

Both cases could also be a wheel hub bearing.

There's one usual suspect if there's no play in the ball joints or tie rods though: the front body mounts or frame isolators wear down and make all sorts of noises. Mine sounds an awful lot like a failed ball joint going slow over speed bumps right now. Bet that's it if you don't feel anythijg driving or see any play...

As far as the "wet," it's just grease seepage. That's normal.

Good to know, that is re-assuring. I was freaking out if I had to change a bunch of components, but this gives me more peace of mind.

I had time yesterday to go out and jack it up without snow and rain. Everything seems nice and tight.

Interestingly, it’s usually the first bump after I start driving that causes the clunk - almost like metal to metal contact.
I also took the car on a gravel road with steep-ish banks. Turns out just driving on the gravel - no sounds. Get it up on the banks where the body “leans†and then I can replicate it each time.

Makes me think this is indeed the body mount(s) like you said.
Is this something that I can fix in the spring or does it need immediate attention?
Also, how hard of a job is this?

Not an emergency, and not hard. Just makes a clunk noise that's annoying. And yes it's often temperature dependent.

Well, unless yours are seized with rust like mine, then it could be hard. I gotta go figure that out :wink:

That’s good to know.
Ha! I’ve been following that thread of yours and I have no doubt I’m going to have similar struggles as you. I’m hoping a few days of PB Blaster soaking will help

Moog tie rods

Postby weaver » Sat Feb 01, 2020 1:15 pm

Hello. I had my tie rods done in December (Moog problem solver) and mine really seeped also. These parts have what's called "gusher bearings", and a special grease boot that allows you to flush old grease out when you service them.(comes out of the top of the boot) My problem was that I over filled them a little bit, so the grease wouldn't stop seeping out of the boot. Was driving me nuts (not hard to do :D ) ! I took the zerk fittings off (7mm wrench) and gently pressed on the boot to remove excess grease(it oozes out down from the zerk mount hole),wiped it all clean and CAREFULLY
re- installed zerks. Finally took care of annoying mess. !!The zerks are easy to cross thread and/or strip!!
