I used wheel bearing shims. Not a perfect fit, but probably good enough. I don't think I am qualified to comment on the effectiveness, there are too many odd ball things on my car.Ken Freese65 BJ8

I have not tried the roller bearings in the top trunion, so I cannot comment on how effective they are in reducing the overall steering effort required as compared to a correctly set up & lubricated original front suspension. However, simply as a warning to anyone reading this discussion who is not completely familiar with all the issues, I have read that they (trunion roller bearings) may require shimming to obtain the proper clearance (vertical end float) of the kingpin & it is my understanding that this is especially difficult because no shims are available or machining may be required.

Hi John,Thick oil/ Penrite Steering box grease will also make the steering heavier. So will under inflated tyres.So will an Unlubricated top Trunion phosphor bronze thrust washer, or poorly shimmed. I.e. Too tight. So will a smaller steering wheel. So will wide tyres. So will thick oil in the steering idler box. So will too much castor.  I have wide (6 inch) tyres, heaps of negative camber, and a small steering wheel. I run 32 - 34 PSI in the front tyres, 2lb less in the rears. 
Yes - Penrite type steering box grease will make your steering heavier. To get it back to "normal", I also run these. https://www.ahspares.co.uk/austin-healey/big-healey/suspension-front/top-trunnion-bearing-kit-pair.aspxNo commercial interest. 
Try Roller bearing top Trunion bearings.

Hi Gary,
Fitting is near identical to using the original phosphor bronze bearing, exc=
ept you use the needle roller bearing. i.e. You replace the phosphor bronze b=
earing with the needle roller bearing.=20
You have to shim the trunnion irrespective of which bearing you choose to us=
e.=20
If you rebuild your kin pins and don't use a needle roller bearing you still=
 need to shim for correct vertical end float.=20
And shims are available from most of the usual suspects.=20
E.g. https://www.ahspares.co.uk/austin-healey/big-healey/Suspension-Front/SH=
IM-0004-trunnion-bearing.aspx
Lots of other people have fitted them over the past 10 years, and I'm not su=
re why you'd need a machine shop to get involved?

Hi John, 
Thick oil/ Penrite Steering box grease will also make the steering heavier. 
So will under inflated tyres. 
So will an Unlubricated top Trunion phosphor bronze thrust washer, or poorly shimmed. I.e. Too tight. 
So will a smaller steering wheel. 
So will wide tyres. 
So will thick oil in the steering idler box. 
So will too much castor. 
I have wide (6 inch) tyres, heaps of negative camber, and a small steering wheel. 
I run 32 - 34 PSI in the front tyres, 2lb less in the rears. 

Yes - Penrite type steering box grease will make your steering heavier. 
To get it back to "normal", I also run these.

BCS (Nocks') have the shims for the trunion needle bearing kit they sell.
