Listerati,
I have been reading through the archives in preparation for a renaissance
of my TR4's front-end suspension.
New springs are necessary, new shocks are a possibility, new bushes are a
certainty.
>From what I have read, replacing with rubber bushes is out of the
question. Of the alternatives, some have chosen bushings made from a
nylon-type material, some have opted for polyurethane, and a cosmopolitan
few have combined them (poly-lower and nylon-upper, as I recall).
My questions:
1. Have those who opted for nylon found the feedback too harsh for regular
road use?
2. Have those who opted for polyurethane found the wear excessive?
3. Have those who combined bushings achieved what they sought?
4. For those who fitted the bushings themselves, is the reaming achievable
using hand tools, or is a lathe essential?
5. For those with polyurethane, did the application of grease prevent
squeaking?
I don't race, though I'd probably describe my street driving as 'spirited'
(a brake booster is also on my list). I'm leaning to all-polyurethane,
pending your insights.
Also, who do the list see as the bushing supplier of choice? TriumphTune,
BPNW, Moss, Revington, TRF all get regular mentions.
Many thanks,
Brian in Valley Forge
