Urethane Vs Gt 335 Bushes

[PAH]

Hi Guys,

I guess we've all chopped out the factory diff and rear trailing arm bushes in our XR6T's at 40k clicks or earlier. I've been in rental XR6's (no turbo of course) that have bush symptoms. What hope do they have with turbo torque, let alone the torque of a tweaked turbo?

I am running urethane diff and trailing arm bushes. The diff bushes went in first, then the training arm bushes earlier this year. I was told by a guy who would no that urethane traling arm bushes tend to produce vibes at around 100 kmh and his warning seems to be correct. The car now has what sounds like an out of balance tail shaft or an out of round tyre at 100kmh. This problem became apparent after the trailing arm bushes. It was OK with just the diff bushes.

So what are the options? I hear that Pedders have just released an after market kit. I wonder what that's like?

Shirley (apologies to Ted Striker) the 335kw FPV supercharged V8 must have beefed up rear end bushes? If not, how long do the factory bushes last in these cars? If they are beefed up, will they fit into an XR6T??

Super pro comfort series, that should be all you need

Agreed, mine have been going strong for over 30,000 klms

That's what I've got in the diff bush. They're Super Pro in the training arms and I think they're the comfort option. Big purple bushes with flats on the edges. If you guys are running these without vibrations at around 100kmh, maybe I had better double check the tail shaft and tyres? The bushes might be OK. I might be putting 2 + 2 together and coming up with 5??

Yep, no rear end vibe at 100 here

A bush will only transfer vibration, unless installed incorrectly it cannot create a vibration.

Yep I've been told about the super pro bushes and people not greasing a certain part, bush itself maybe? And of course in the instructions it says you need to and when you don't is when you have troubles.

That's what I've been told and the old mans fussy/meticulous with stuff like that, and said if I ever get stuff by them make sure they follow the instructions! Lol that true pat? Seeing as how you're the pro here

I've had superpro bushes in for sixty thousand K's now. Well 2 thou short of.

I don't have the comfort :( dont think. Dark blue.

Anywho...goood shoite.

I have them with Teins so the car is stiffish. I keep thinking either the Teins or bushes will need replacing soon. Each service they seem to come up fine.

Really thought the rear blades would have worn out by now.

Never had a vibe or shudder with them btw. And you will feel if you have one with the poly bushes.

I just put on crap feral tyres and now I have a little rumble from the back around 100. For the first five K's of a morning it feels like the tyres are out of round.

Bloody horrible and I am throwing them off next pay.

No such thing as a good cheap tyre.

So yes there are a lot of angles when modding hey.Move up a step and the cost goes up all round.

I had to get bushes done only a few mths ago for road worthy and they were factory Ford jobs. I'll likely change them to SuperPro Comforts again this year. it's not the cheapest job to get done so do it right first time and save yourself good dough

Superpro comforts here for me as well. I did them when my Truetrac went in just figured as above to do it right once.

Very little increase in NVH, maybe a bit more tyre noise. However if the car has been sitting a few days I get the flat spot vibrations until the tyres(factory Dunlops) have warmed up a little. Have found running high pressures(44psi) helps reduce the tyre flat spotting when sitting for lengthy periods.

Out of interest Senna_T what is the cost of all the superpro comfort bushes for a BF ute? Front, rear the whole lot.
