    Control Arm Bushing Noise

    I've had some pretty loud low pitch squeaks on my passenger side for some time. It's annoying. I replaced the tie rod ends and ball joints today... which was surprisingly easy... everything basically fell apart and it only took about an hour for both sides. The control arm bushing are certainly original and look bad but I'm not ready to tackle them just yet.

    Are there grease fittings for the control arm bushings?

    Will not replacing them while replacing the other suspension components impact the new parts and alignment?

    I'm getting new tires and alignment soon. Should I put that off until I can get around to doing the control arm bushings?

    Re: Control Arm Busing Noise

    4wd vans have a place for grease zerks, 2wd vans do not. Any time you replace parts on the front suspension, an alignment should be the final step. I would recommend you replace the bushings now. If you need to put a bunch more miles on it before doing the bushings, then get an alignment now, then again after doing the bushings.

    It's a little late now that you've done the ball joints, but if I were doing ball joints and bushings, I would probably just replace the entire a-arms. You can get the entire 2wd upper assemblies for $65 each, and lowers for around $68 (bushings and ball joints included). Tim

    Thanks Tim. That would have been the ideal route to go. Not sure why I didn't think about replacing the entire assemblies. I'm sure that's what the shops would have done .

    Good to know!

    Tim,

    I am unable to find the part numbers for the UPPER control arms on the MOOG website for my 1984 Toyota Van. They only list the two lower control arms as does Rock Auto. Are any of those numbers you listed for upper control arms for an 84?

    Re: Control Arm Busing Noise

    Yeah, Being 1984 I'm not sure what to tell you. Those part numbers I posted above are for 85 - 89 2wd Toyota Vans. I'm not sure what makes 84 different or if they would interchange, but doesn't look like you can get Moog uppers for 1984 (at least not by application). I checked Toyota's EPC and see they also list different part numbers for 1984.........but they want close to $400 each. I tried crossing those numbers but nothing came up. Tim

    I do appreciate that you checked on that for me. The torsion bars are the same on 84-85 so if the upper control arms for an 85 accept the torsion bar bolt on bracket, the 84 should as well. Maybe I will check to see if the upper ball joints cross over as well. So far, I relaced the torsion bar on the left side a year ago and stopped short of messing with the bushings even though I have them.

    Definitely let us know if you figure anything else regarding interchange as it may end up helping somebody else down the line. Tim

    Re: Control Arm Bushing Noise

    I was wondering the parts from Rock Auto for 2wd lower and upper assemblies (bushings and ball joints included)
    Moog #RK621261, RK621260, RK641388, & RK641387

    Will be OK for a '84 Van?

    So sometimes I have a sharp quick noise when i'm turning my steering wheel on the right and I don't know what is it.

    Any help will be appreciate, to tell me what should I inspect and figure out the problem

    Thank you!!

    Re: Control Arm Bushing Noise

    I'm changing my rotors and pads... And I thought it will be a good idea to change more parts while I will have the space.. So I just ordered from AutoRock 2 Stabilizer Bar Link for both sides (MOOG K700528).
    I have added some pics below, can you please tell me which part is the one in the cycle? Is it my upper ball joint? Bc in Rock Auto the part looks different, I'm confused? Also if I want to replace only the bushings can you please help me find the parts? Or I may have to replace more parts if there are really bad, please let me known I'm happy to hear your recommendation.

    Thank you very much!!

    Re: Control Arm Bushing Noise

    With some research, I think the name of the part I asked above, called Steering Knuckle and on top of it is the upper ball joint.. please let me know if Iツ知 wrong..
    So by changing the rest of the parts, I will go and order the upper and lower ball joints as well.. so I can be more safe.

    Re: Control Arm Bushing Noise

    IQ - you are correct

    I understand the thought that new is always better, however.

    The reality is that factory parts are of better quality and if you were installing OEM we wouldn't be having this discussion.
    Reality is that some A/M parts can be of lesser quality (shorter service life).
    If the ball joints are within spec and not seized, I would not change them.
    YMMV

    Re: Control Arm Bushing Noise

    Burntboot thanks for your reply!!


    You are totally right!! I知 not sure if they are the original ball joints but from the pics are not looking that bad, I will check them out while I知 working on the van changing the other parts.. I believe my Stabilizer Bar Links are in a really bad condition I知 feeling it every time I drive the van, also sometimes I知 getting a quick sharp noise from the passenger痴 side when I知 turning my steering wheel.. what should I check for that?

    Re: Control Arm Bushing Noise

    Those link ends do look old and cracked and definitely the first place to start.

    The Van is the same as any vehicle, really.
    Check anything made of rubber, both visually and with a bar.
    If you see rubber with cracking, then its due for replacement.

    The rest is just checking for play.
    Easiest way is a long screwdriver or prybar, (1-2ft) and GENTLY apply pressure, then watch the how the bushing behaves.
    Generally speaking mounts and bushings should give a bit, but resist movement and return to normal position once released.
    Anything that jumps &/or doesn't return to position warrants further inspection and likely replacement.
    Sometimes you wont even see the movement, but will feel it thru the bar
    And please, be careful what you pry on and against, last thing you want to do is damage something else.
