Because we're running an EVO DTD suspension with an EVO Lever System in the rear, we've had to modify our exhaust so that it dumps in front of the rear axle. While this didn't seem to be a problem back when we were still running a 3.8L V6 motor on Moby, we did start to see or should I say, "hear" a problem after doing an LS swap. The problem was that we tried to keep our exhaust California legal (being that at the time, we still lived in California) and that meant we needed a third cat in place and in front of the muffler. This in turn pushed the dump further back and closer to the rear axle or more importantly, closer to the control arm joints. Thanks to that and the greater amount of heat coming from the exhaust, we've found that the grease in the Johnny Joints here would get cooked and that would allow them to become very squeaking in a short amount of time. Over the past year, I've tried a number of different greases to see if one could withstand the heat but with no real success or should I say, up until now.
Perhaps it's too early to say but I recently started using Royal Purple Ultra-Performance Grease (UPG) on my joints as it's supposed to be a high performance synthetic grease that is also stable at high temperatures. As far as grease goes, it isn't the cheapest you can get but then, like most of Royal Purple's products, it does seem to be working a lot better. Certainly, I've held off on making this post until I had a bit more time to test it out and so far, it seems to be keeping my joints squeak free a lot longer than before. With any luck, they'll just stay squeak free but already, this grease has extended the service interval or need for reapplication and I'm really happy with that.
Anyway, for those of you who are looking for a good lube to use on your Jeep, I'd have to recommend Royal Purple Ultra-Performance Grease. :2thumbsup:
