dblenk Posted June 16 Report Posted June 16 (edited) Superpro always lubricated with the grease for the suspension etc do you grease it for the steering rack i would think not as it would help it move always fitted rubber so first time with poly anyone with experience ?? thanks David Edited June 16 by dblenk Quote
PodOne Posted June 16 Report Posted June 16 Hi Dave Why not fit solid mounts to eliminate movement? Andy Quote
dblenk Posted June 16 Author Report Posted June 16 the poly ones came in the set are the solid ones fit and forget i normally do std gear but was told the rubber is not as good these days it wasnt anything to do with performance stuff i could be wrong but the solid ones transmit and the bumps etc into the steering ???? not sure David Quote

I fitted PUs to keep it "slightly" elastic, indeed this is not really "elastic". Edited June 16 by Z320 Quote

Turned out the hole through the solid mounts was a fraction larger than the rack diameter. The mounts were from TRGB and the 2 halves are the same width, about 15mm, the ones on my car have a wider lower section +-40mm which locates against the flange on the rack giving extra lateral support We ground a millimetre from the face of the 2 halves of my friends mounts and they now grip As for fit and forget, mine have been on for in excess of 20 years of daily use without any issues George Edited June 16 by harlequin Quote

David I'm sorry David it was so long ago I really can't remember. At the time I bought lots of parts from a place near Middlesbrough (Sedgefield ?) but they have gone out of business, the important thing is to get the type with the wide bottom section so that the rack cannot move sideways.

dblenk Posted June 26 Author Report Posted June 26 (edited) when fitting the new bushes can it be one side at a time or is it best to remove both so the rack is easy to move about i was thinking if one side at a time no settings are changed makes sense to remove both though ?? i havent removed the track rod ends either i am happy with the tracking etc got it done last year Edited June 26 by dblenk Quote
dblenk Posted June 27 Author Report Posted June 27 question the superpro polys are 2mm larger than the standard rubber ones i have hence a bit of a pain are the polys supposed to be larger ??? David Quote
harlequin Posted June 28 Report Posted June 28 I'm surprised to hear they are bigger, maybe it just the old aftermarket parts quality problem again. I have a couple of sets of polybush amongst my spares, if no-one else can advise you David I will dig them out this afternoon and measure them. I have always struggled with fitting the standard type arrangement which is why I have gone for the solid type George Quote

David Bigger in which direction, please? Your ? Let me suppose you did not try to fit it on the car? Are your standard rubber ones new or old? 2 mm too small? Your question causes multiple question to me. Edited June 28 by Z320 Quote
dblenk Posted June 28 Author Report Posted June 28 (edited) Everything is new i will ask TR shop for the dims of a std one tomorrow to check the old one is correct with the new rubber i have except the hole in the middle hence the movement think i am going back to rubber then if they go in a few years i will just replace them david Edited June 28 by dblenk Quote
dblenk Posted July 1 Author Report Posted July 1 all fitted and torqued up using rubber i had 1/8" gap using mole grips either side 22NM 16lbft but looks they sprung a little so gap is 4mm ??? brackets are touching the chassis rocked the steering wheel steering rack moves slightly maybe 1/2 a millimetre is this ok i have never looked on previous cars ?? thanks David Quote
TR NIALL Posted July 2 Report Posted July 2 (edited) Surely there should be no movement of the Steering Rack. Edited July 2 by TR NIALL Quote
Z320 Posted July 2 Report Posted July 2 Any movement of the complete rack sidewards makes your steering wheel out of control being twisted slightly left and right, or not. Are you sure the whole rack moves and not only the steering gesrbox on the steel tube (this was my problem, another thread) Ciao, Marco Quote
Ralph Whitaker Posted July 2 Report Posted July 2 Surely the rack is designed to move slightly otherwise what would be the point of mounting it in rubber. Ralph Quote

stuart Posted July 2 Report Posted July 2 3 hours ago, Ralph Whitaker said: Surely the rack is designed to move slightly otherwise what would be the point of mounting it in rubber. Ralph It shouldnt move as the mounts are designed to hold the rack tube in both horizontal and vertical plane. Stuart. Quote
dblenk Posted July 2 Author Report Posted July 2 24 minutes ago, stuart said: It shouldnt move as the mounts are designed to hold the rack tube in both horizontal and vertical plane. Stuart. looked again think its just a bit of flex int eh rubber mount no more than 1/2 millimetre definitely not 6mm like previous Quote
DaveR Posted July 2 Report Posted July 2 Most of Standard Triumph's work changing to rack and pinion from the steering box was carried out when developing the Triumph Herald. When the car was introduced in 1959 it had solid mounts. The motoring press reviewed the Herald in 1959 and complained about rough roads being felt through the steering. So from 1960-on the Herald was fitted with the rubber bushes. This resulted in all subsequent Triumph models fitted with rack and pinion getting the rubber bushes. I changed to solid mounts on my Vitesse over 25 years ago and haven't noticed any vibrations problems through the steering on rough road surfaces. No sense no feeling I guess! Dave Quote
