Patrol suspension specialist HELP

Postby kobusb » 15 Mar 2017 13:07

Hi Patrolers

My Patrol has quite a violent shake/vibration on the front suspension when I brake on a downhill.
My previous Patrol had a similar problem and a catastrophic failure when the front bushes of an aftermarket suspension fitted by a bunch of crooks in Pretoria disintegrated going down the steep downhill between Pietermaritzburg and Durban.
I do not think that the current problem on my new Patrol is the caused by the original bushes as the vehicle has only done 25000km, It stood in the bank's repossession warehouse for months.
Can this problem be caused by the steering damper shock? How do one check this shock absorber?
I would really appreciate some advice and a suggestion of a Patrol suspension specialist in Gauteng.
Kind regards

The steering damper cannot cause any type of wobble. It can only mask it.

If the problem only happens under braking, then the chances are pretty good the cause is warped front bdake discs.

Play in any of the joints, bearings or bushes can amplify the problem. As can wheel balance issues or bent rims (or rims not bolted down straight).

If you want to bring it around (and if we can find a mutually suitable time) i can have a look, but i am not making any promises.

I have a sneaky suspicion that you have aftermarket mags on and they are not seating properly. With such low mileage the bushes should still be good. The brake discs too should still be good, however they could have gotten warped with heavy breaking and heat build up and rapid cooling ( possibly from going through water seeing as we had so much rain as of late ), but I still have that feeling that there is a mag wheel issue or rim seating issue.

Peter will definitively be able to give you solid advice and input.

If it's only under braking I would first look at the brake discs. Sounds like
Warped discs to me.
