Tight wishbones
Just fitted my wishbones. Can you tell me if they are suppose to be tight when moving them, they do move but have resistance to them. Also the RH
front lower is tighter than the others and squeaks badly. Lubricated well but still no good.
Will they bed in or do I have to sort them out now.
Thanks in advance

A bit of resistance is normal.... They'll likely soon free up once the car is bouncing around....

Cheers - saves me taking them all off again
What about the one that squeaks like a Bar steward?

How far are you moving them?
Probably a lot further than they will ever travel with shock absorbers fitted and the car's weight on them.

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

It squeaks as soon as I move it.
Happy now they may resistance just need to sort the RH lower one out

Just don't put one of those gold coloured band thingys on the upper strut,
that makes the wishbones lock solid after a couple of years and
it never stops making noises,
and rarely works again,

i had an old Golf that sqeaked when i ploybushed it. Drove me mad. Im so pleased the Mac#1 doesnt do it.
What grease have you used and where applied. Just wondering if the type makes a difference. Ive noticed a few MK's squeeking before, maybe its
just one of those things.

I have used vaseline - which Mk advise in the build manual. May have to get some proper stuff though. Any suggestions?

They are a right job. Good abused with a wooden mallet helped me + Silkolene RG Racing Grease.

Did you check all the crushtubes are slightly longer than the width of the bush, else it will be tight.
I had to put a ship washer on some to make sure they did'nt bind

I used a silicone based grease on mine, red in colour i'll try and find the actual name later when i go in the cave.

The stuff i used is called RED RUBBER GREESE from CASTROL. Think this is what Bob's talking about.

Sorted it out last night.
Removed the bushes and filled down the excess weld that was causing the bushes not to sit flush. Couldn't tell until the bushes were removed.
But after filling them made sure the metal inserts were slight bigger then used vaseline. Job done well sort of, going to get some better grease and
do the lot again.

Hi All
To save me reposting an already discussed topic-
I'm rebuilding my Megablade at the moment, have just had the chassis back and started to have a go at the wishbones this evening (I'm
using Nylon bushes). I'm finding that getting the wishbones into their mounts is a tight fit- they do go in and move around, but you can move
either of the ones I've fitted and it'll stay in the same place, regardless of angle. The previous comments on this thread have talked
about them 'bedding in', so not sure if this is normal or not, as it's my first build/rebuild.
When the wishbones are in and bolted (loose fitted), the bushes press against the mounts and the wishbone swivels around the bush. I'm sure
that's not normal, but I've not really got any other ideas?
Also, received my shocks and springs from pro-comp the other week, the bushes in these also appear to be too big for the mounts, but I'm
guessing the rubber and the crush tube could be filed back to fit? Am I ok to do this?
Thanks in advance guys!
Ben.

I am really tempted to drill and tap the wishbone and screw a grease nipple in how much would this weaken the wishbone if any or has anyone else done
this
Life is like a bowl of fruit, funny how all the weird looking ones are left alone

If the wishbones pivot on the bushes when loose fitted you have a real problem.
Did you grease the outside of the polybush to fit them?
Actually even if you did, on loose fit friction should still prevent this!
Wrong size bushes?

the crush tube inside the bush should be slightly longer than the bushes, if your bushes are fouling you can shave a bit off so they fit inside
without fouling the chassis mounting brackets.
the crush tube takes the load when the bolt is tightened and stops the bush its self taking the load which would result in a very stiff action on the
wishbone.
grease the outside of the crush tube to prevent squeaks (as said all ready silicone grease works best)

This is all totally correct, (though silicon grese may dry out quickly) BUT, if the wishbones are pivoting on the outside of th bush now, they still
will when it's all bolted up tight

A bit of Moly grease will do it but I would also look at bending the bracket a mil or flatting off the polybush, inner tube and outer wishbone tube
with wet & dry.
What I would call "Fettling to fit"

I ordered the bushes from Westfield specifically for a Mega style car, so they should fit according the guys there. The crush tube is about the same
length I think as the bushes, possibly a little smaller, so I need to file the nylon part of the bush down, so that the crush tube is the longest
part?

I did grease the outside of the bushes before fitting them to the wishbones, yeah. I had the chassis shot blasted and re-painted, so I've filed
and sanded off the paint from inside the brackets back to the zinc layer, but it's still a little on the tight side. I'm assuming that the
wishbones need to pivot by rotating around the crush tube, rather than the bushes themselves taking the load. So if I file back the Nylon so that the
crush tube is the longest part, this'll take the load off the bush?
I've also had a similar problem with trying to fit the shocks, the crush tube is the correct length, but the rubber bush that sits around the
outside is too long and stopping the assembly from lining up with the mounting points. So filing the rubber back will keep a longer crush tube that
will fit, I hope...
Does that sound about right?

too answer all the questions
yes
all these bushes are quite often slightly too large to account for variations on chassis brackets so just keep taking material off the width of the
bush until the crush tubes are slightly longer, turning them down on a lathe is best option
