General TR Poly bushings long term results

[rooster]

Hi,

I am considering using poly suspension bushings in my rebuild. I'd like to hear from those who have had them for installed for a few years... how often do they need to be lubricated to keep from squeaking, if at all?

Has any one tried the newer graphite impregnated ones? Do they require lube?

Thanks!

I put poly in my TR6 about 10 years ago. The only time they squeaked was during a 3,000 mile trip. It was driving me crazy. I visited a local store, purchased some silicon spray, and blindly sprayed the offensive area while pushing the car and down. I suppose a piece of stone or something was lodged in there, and once removed, the noise stopped. I used them when rebuilding the TR3.

Thanks, that's good to know.

Does any one else have anything to add?

I used poly bushes in the front and rear suspension and on the steering rack when I rebuilt the 4A about 13 years ago. They are holding up very well. The ride might be a little harsher than standard but I don't have a basis of comparison as I never drove the car with standard bushes. I have harder springs front and rear as well. I would go with poly for better handling and longer service life. On our recent 4600km trip with 2 people and luggage, the ride was very comfortable. Although as the picture shows, we did fit a bit of stuff in....

Nice 4. It's surprising how much you can fit into one of these. I once carried a full size bicycle in my 6, with the top up.
