Cone sure-grips don't have thrust buttons. Did read last 6/7 posts, if somebody said that sorry.
The best option is to use the original tapered rear axle bearings these cars were born with. It is a great design, way ahead of anything else.
They will outlast the car if you clean and repack them.
WHY???? it's fun to poke the hornets nest.....complacency can become addictive....and to overcome it, involves thinking and reasoning rather than accepting the "they said" principle.....???Get over the Timken/Green Bearing debate for the love of Christ!
Should not happen if the housing is vented?I had a problem seating one side. After having it together for two years I removed the axels to replace the center section. Reinstalling the axels one side didn't want to seat. I could push it in by hand and it would push back out. It ended up being the grease I used on the bearing and seal was creating a seal and pressure was preventing it from going in all the way.
If yours is hitting something solid, it's more than likely the thrust button. If it's spongy and pushing back out it could be what I described.
