Just after a little advice.

I have one of those sh..ty grease guns you get of ebay for about £10.  And I cannot get grease into my front beam with it.  What do you guys do ?  It's not worth buying a new one as it's the only job I have for it.  What's roughly the cost to take it to a garage and get them to power grease it ?

First unbolt the grease nipples and give them a clean, they are first in line for road crud

Shouldn't need much pressure ttget grease in

Try the gun on a nipple off thecar

Check grease hasn't hardened up inside the gun

Good luck

A small local garage won't charge much. 

I had an A-frame greased for free my mine.

Yes remove each nipple. Clean end of each. See the little ball in end. Push the little ball in over with something suitably pointed and then in and out until ball moves freely. Just watch you don`t slip and stab your hand as you push. Clean the threaded hole as best you can also.  The simplest of grease guns should then be fine.
