suspension noise

ranger · Postby **ranger** » April 13th, 2012, 10:23 pm

help needed, i'm hearing a knocking sound coming from my front suspension(2010 ranger) had it checked by quite a few reputable persons including the firm.....nobody found anything wrong but the knock continues. bushings, ends, ball joints, torsion bars....everything checked, lubricated and tightened.....anyone encounter this before....any advice/suggestions????

describe how the knock comes about - i.e. when and how does the knock occur? Where does it come from? How often?

Is your alignment staying in tact or is the vehicle skidding easily on corners?

ranger · Postby **ranger** » April 14th, 2012, 10:13 am

it happens when i cross a hump, sometimes not all the time when i corner at full lock(not the turn stop noise), during up and down movement of the suspension....however driving fast through rough roads you hear nothing....suspension is solid apart from this noise, no steering issues, no alignment issues, no tyre issues, no handling issues

oh and it comes from the front on both sides left and right

are your pitman arms and sway bars good? What about the velocity joint bushings?

huh!? Those don't have bushings yo!

Check the sway bar links and bushings.

Is it a metal impacting metal sound? or metal rubbing against metal sound?

Had a similar problem when my ranger was new. I was told that it's the torsion bars that are making the noise. Take it back to the firm and have them do a full lube job on the front suspension. Please note that it WILL take some time for the grease to settle into the joints, so you may have the problem for a couple more weeks... or it depends on how much you drive your truck and where.

When I was informed that the grease had to settle into the joints, I used to take a 'quick' detour through a rough road every evening on my way home from work to "exercise the suspension." 8-)

Sounds like torsion bars to me.

are you sure that it is the front that is making the noise :?:

wheelnuts tightened :?:

pitman arm and sway bars good, links and rubbers good, i did take it back to the firm they did apply grease but i've always kept my unit well lubricated so i don't think its a lubrication issue and my suspension get regular exercise, wheel nuts checked also and yes i'm sure it coming from d front.
its a metal sound, somewhat like a slack bolt that moves when the suspension moves making "tocks" sound. nothing slack was found though.....and like i say had some reputable persons check it out.

Cooper · Postby **Cooper** » April 16th, 2012, 8:58 am

It is usually the front part of the torsion bars (where they connect to the front cradle arms) that makes the noise. There should be some grease packed around that joint where the bar itself connects to the mount. If that is already packed with grease, you should be good to go until the grease can work its way into the joint.

BTW, did you do an underwash sometime before the noise started?.... sometimes the guys at the wash bay will take out this grease and they might hold the nozzle of the pressure washer on the joint too long, which will force water into the joint resulting in suspension noise.

no underwash done, but i'll recheck to see if that area is properly greased...thanks

ranger · Postby **ranger** » April 17th, 2012, 9:04 am

ranger · Postby **ranger** » April 27th, 2012, 10:16 am

have you checked your indicator fluid levels?
Also make sure that the conflagulator is fully topped up.
