Nolathane Diff Bush Noise Fix?

[SuckSqueezeBangBlow]

digging up and old thread,

has anyone used these diff bush inserts? (they apparently fill the voids in the factory bushes)

however if you read the top link, it seems like they only work with one sort of factory diff bush and its not made clear which models DON"T have the offset crush tube.

any thoughts?

anyone? I think I'll get one either side of my bush if possible.

BA....offset????

BF....centred???

Pat?

there seems to be an offset washer with their offset bush set perhaps you could use this on their 'void insert' bushes anyway.

Yes, BF is a larger bush with the crush tube in the centre. The BA bush is smaller with the crush tube towards the top (offset)

The void fillers seem to only work with the BF bushes, however they don't seem to hold in the bushes that well - we figure if you have to take the bolt out to fit these "void fillers" in a BF you might as well spend an additional 15mins to take the old bush out (which will most likely be cracked anyway) and throw a complete replacement Super-pro unit in and be done with it.

Hows this for mechanical abuse, I've had both the comfort option and race version in my car and they look like brand new, after numerous re-steps and launches with 500rwhp - we even re-used my old race spec one in a customer car (he knew it was used) and its fine. Results speak for themselves really.

I was thinking you could put the 'void filler' bush in without having to lower the whole rear assembly. I'm happy to drill a hole in the wheel well to get the bolt out, but I didn't think you could then remove the bush using this method as I thought you would need a press to get a new bush in there?

[senna_T]

Nah, no press needed for the super pro ones, you just use the grease provided and tap them in with a rubber mallet - if you have a plate to put over it while you hit it in, things are a little easier

What are the inducted noise levels like with the Super-Pro bushes Senna? Are they as quiet as the factory items?

[senna_T]

The race spec ones are known for transferring noise, that's a fact. The comfort ones are very good, maybe a 5-10% increase in noise if that.

The biggest problem is the wear on the car. As I'm sure you can appreciate, a bush cannot creat a noise, it can only transfer an already existing noise into the vehicle. So the main variance we have seen is when a vehicle has a worn diff or CVs there is more noise apparent when the poly bushes are installed.

We've fitted plenty of these for members here, all of which have been happy. Even when we put the race spec ones in my car, the performance gain out-weighed the noise increase (for me anyway)
