I am about to re-grease the bearings on our Jayco. Does it matter what type of grease that I should use?
I have in the man shed an all-purpose grease.
Will that do the job?

I use one with a molybdian content from Valvoline.

Wheel bearing grease is cheap, Id rather have half a tin of GP grease on the shelf at home than try to change a wheel bearing on the side of the road.

Ideally, you should use high temperature grease for wheel bearings, but all-purpose grease will most likely do the job anyway. I was given a large drum of general purpose grease years ago, and that has done well for me. My caravan has done well over 100000 km now and I have had only one wheel bearing failure, and that was from a brand new bearing. I had replaced both sides of my caravan because of the age and distance travelled, and the new bearing failed after only 2000 km.
I always carry a spare bearing, already primed with grease, ready to fit roadside if necessary. This got me home safely and I then fitted new bearings of a reputable brand to both sides. I suspect that the failed bearing was slightly out of tolerance because the outer cup was nearly impossible to remove - it actually shattered before I got it out.
Regarding greases, grease is merely heavy oil, with a carrier - typically a lithium based soap to keep the oil in suspension. Additives are added eg Molybdemum Disulphide (anti wear) or stabilisers to maintain the viscosity (thickness) at higher temperatures.

If doing any water crossings consider boat trailer spec grease.

The Nulon Red grease in the black tub with red lid from Supercheap is by far the best wheel bearing grease I know of. Not cheap but worth it.
Had a Peugeot 505 sedan for lots of years a while back...was always adjusting front wheel bearings around the 40000 km mark with so caled wheel bearing hi temp grease.Got a bit jack of that so installed all new bearings and seals with the Nulon grease....never had to touch them again for 250000 k ...always checked every 5000 k service for play and noise. Car ended up doing 760000 k before I sold it ....and one wheel bearing just needed a nip up in that time. Highly recomend the Nulon grease here.
Cheers Keith

Any wheel with brakes needs to have a high temperature grease.
No brakes reduces the temperature requirement.

I agree.
If you have brakes, always use high temperature wheel bearing grease.
Caravan brakes can get hot enough to melt the grease out of the bearings with GP grease and a failed bearing will be the end result.
It is a bit like pouring engine oil in your gearbox. Yes it is lubricant but for a different purpose, and failure of the components is just a matter of time.

Thanks for your input on my request.
I just purchased a tin of "high-temperature wheel-bearing grease." from Auto Barn.
yes, it pays to seek advice.
Thanks

Up-date.
I have completed the procedure of greasing all 4 wheel bearings on the caravan. I used the grease recommended by you guys.
Packed plenty pf grease in and around the bearing.
The process was very easy and as always I get a lot of enjoyment of D.I Y ( do it yourself.)
thanks for the tips etc.

Best not to use molybdenum based grease, bearing rollers tend to skid around inner and outer races, high temp. Marine grease probably best.
