Hopefully just needs the poly bushes removing from the wishbones,cleaning up and regreasing.
Could be the crush tubes in the bushes have gone rusty though and will need replacing,does need looking at sooner rather than later as if the crush
tubes are rusty enough to be seized in the bush it can cause wishbone failure.

Ok thanks that's very helpful. I try to take a look.

I'd second the above advice - dismantle the wishbones, bushes and crush tubes, clean and apply fresh grease on reassembly. On my MK Indy I did
this on the first winter and it made quite a difference. Free rotation and less noise too. I would also add that it's worth paying attention
to the length of the crush tube vs the distance between the outer faces of the bushes in the wishbone. If the crush tube is too short it can make the
bush bind in the chassis brackets, If the crush tube is too long it can allow the bushes to slide back and forth along the crush tube. IIRC I had to
file a couple of crush tubes down slightly to achieve a crush tube length of +0.5mm longer than the distance between the outer bush faces.
Hope that helps and some photos of your work would be useful for us to observe and comment on.
ETA...I did think I'd like to add grease nipples to the wishbone tubes where the bushes go. My reason being it would mean you could inject more
grease into the bush in situ. My reason for not going down this road was my perceived idea that it might weaken the wishbone tube and you'd
have to trim the bushes to give space for the inside of the grease nipple.

HI Hazard. Im in the same boat as you. Just started stripping my new creaking Indy.
Thankfully my crush tubes/bushes seem ok, but did need a clean up.
Link is here if your interested.

Would you mind comparing your front upper wishbone mounts to mine? (Bottom set of photos in thread)
Im referring to the gap being taken up with a washer each side.
Do you have any pics of your new Indy?

What sort of grease should be used? Silicone Grease?

Yes, silicone grease. Don't buy the carplan stuff in a tube though, it's more like silicone oil - neither use nor ornament.
Mine creaks on the rear because the wishbone brackets are in the wrong place so the bushes rub on the faces of the brackets. It's on the long
term jobs list, but I haven't remedied it yet.

Also make sure the bush tubes are long enough so the pony bushes aren't pinched by the bracket

I had the same problem on my car cleaned and regreased the bushes but it came back after a few months ( ok I do use it in all weather which might not
have helped). I have since redone them using rubber grease and have had no problems since

Looks like I can buy a whole set for the MK Indy for £70... I think if Im going to go to the trouble of stripping them all down, might as well stick
new ones in!
I also want to get the wishbones powder coated again.... just a question.... will i have to get all the camber / tracking etc setup again when I put
it all back together or is it sufficient just to mark the rose joints threads (so I can put it back together again the same) - hope that makes
sense!!?

New ones should still be greased...

If you can put them back exactly as they were. Should be ok. Just make sure the same wishbone and same rosejoint goes back the same place.

If you're getting new bushes it might be worth getting stainless crush tubes as well. MK usually supply mild steel that rust and cause issues.

Mine creaked loads from new, and the bushes were packed with proper silicon grease. Over the years the creaking has reduced. I have occasionally put
some motorbike chain lube on them which quietens them down.
I should probably strip and check them at some point as they have been together for 10 years now.

I suspect your crush tubes are too short causing the bushes to be clamped rather than the crush tube, easy way to check is bounce one corner of the
car to check
the noise level then slacken off the wishbone bolts , renounce , if the noise is reduced the crush tubes are too short.

Maybe, but when I put them together they all moved very smoothly and quietly and didn't seem to bind at all.
