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.

Try Roller bearing top Trunion bearings.
