Vx are going to be doing a roaring trade in wishbone bushes.  Every one so far shot to pieces

[Taxi_Driver]

If that causes clonking noises when going over bumps......my n/s front are knackered too  

[theolodian]

Another item for the shop?

So how do WIM diagnose them? Is there movement before any visible signs such as splits and cracks?

A pry bar and a well calibrated hand. There's always movement in them, it's just the amount of resistance to movement that counts. (stiff resistance = good, flapping around with barely any provocation = bad).

Probably the best explanation i've seen so far.

I think mines gone on the N/S on my GLS, I have a sticking caliper that doesnt help either, been going to sort it for a few weeks now.  

One day.  :-/

Not in the polly bushes the guy had made but only  4 mths old
No movement at all, but does affect theb feel.

Thanks to Tony and WIM for a very informative and enjoyable day.
And to TB for doing his magic with the Tech2

No thanks to VX for making Sh!t bushes tho, Mine was the second to go down the scenic bushy route, Still FFc gary thought it was funny that everyones was going out that way till Tony kicked the spring out from under his feet.

"OS Rear springs Broken Gary, Can't adjust it". LOL that made my day.

Ode to Gary, Don't laugh at the misfortunate.


Thanks again all.

[Jimbob]

Glad mine were spot on

Got em checked on the Sunday, so I had time to source some for the return trip on Monday

Do I feel a Bush Party coming on then?, I assume its a lot easier on Posters?

Thanks Kevin. No substitute for experience then.

One further question. On a previous forum one highly regarded contributor made a specific point of stating that the front horizontal bolts must be torqued up with the weight back on the wheels otherwise if they are tightened when the wheels are hanging you are immediately 'twisting' the bushes when it is lowered to the ground then further adding to it with the movement of the supension over bumps. He claimed this caused premature failure of the front bushes. I don't recall seeing anything specific about this here (must check) but in my experience it is virtually impossible to do this as when the wheels are on the ground as there is not enough clearance to turn the torque wrench on them.

So is this really a problem and if so how are folks getting around it without a car lift or a pit?

Yes, IMHO. The bushes are seemingly fragile enough. If they are tightened up in the natural resting position they are being twisted one way or t'other from their "resting" state. If they are tightened up with the load off the suspension they are already deformed before you hit a pot hole and the wheel bounces up, so such undulations will put much more twisting moment on the bushes, resulting in them not lasting as well.

You don't have to tighten to the final torque figure on the ground. Nip them up sitting on the wheels then raise the car for final torquing if that's easier - or put the front end on ramps.

Absolutely - this may well have been the cause of the premature wear on my MV6 bushes (I simply followed the book of lies).

This time around, they were tightened on the ground, thne raised to get final torque on.

Would putting the car on a set of ramps qualify for being on the ground?
Got to change mine soon and have noticed the fact about so little room to get under the car so was thinking maybe tighten the bolts whilst jacked up then drive car onto ramps for final torque setting.
