Caterpillar has been saying for years that the original bearing grease is ****. A job well done, Andy.Well my car did not make it down to ADI due to a grumbling front wheel bearing, so here's the tale of the fix.
This is the old bearing I took out, it's a Ruville bearing bought from a well known Audi parts supplier and I'm guessing at the mileage, but it can't have done more than 10k miles


The outer seals were still intact but as you can see there is not a great deal of grease in there and looking closely at the face you can see where it's started to break up, causing the noise

Now, if you search for 'wheel bearing' on here, you'll find on almost every thread user Caterpillar banging on about putting this fancy Mobil grease in your new bearings, so I decided to get some. I couldn't get the grade he used, but after asking the local Mobil rep, he recommended this

So I striped the new bearing, FAG bearing this time. As you can see, still light on lubricant.

Cleaned out the old 'grease' which looked very much like Vaseline!

And re-packed them with Mobil's finest synthetic grease

The first test drive revealed that it's now as quiet as a mouse, so I'll be doing the other side when I get chance.
I'll report back on the long term benefits
an other thing,the grease in the org bearing are some ****,so i use to open the dustrings(use a knife)carefuly,and fill the bearings with the MOBIL xhp222 grease in,and set in the dustrings back,the grease are BLUE coluored. its the grease they use on heavy loaded lorrys.its the BEST grease to use in the most places.in the outer joint and so on.SSComment

I just popped them out by pushing the race out from the inside, didn't need any tools. You'll see once you have the bearing in your hand

Decided I better get my act together and fit the re-furbished subrames and suspension. When I stripped the passenger side I found some rust that I thought I better deal with at the same time and as with most jobs, this snowballed into an all weekend affair!

Bumber and wings off to get the washer bottle out of the way

Rust wire brushed out, and treated, then washed, de-greased and dried.

Unused holes in wing plugged up

Masked ready for underseal

Coated with 3M 08861 and new KW V1 installed

Whiteline anti rollbar drop links installed along with coilover covers

Top tip for front track rod adjusters, wrap them in Denso tape. Mine were wrapped from new, must be over 2 years now.

This is the result when I took it off, no corrosion and the adjusters were free!

Best £7 you'll spend

Forgot to get and pictures of the subrame, but it's been chemically stripped, hot galvanised, powder coated, then coated with 3M 08861 inside and out, it better not go rusty this time!
Now just go to do the same again on the rear

Nice work with the denso tape.
How come you didn't seam weld the subframes while they were being refurbished?2013 Touareg TDI /// #farmenwagen

Pretty certain this is why my Bilsteins failed so quickly, there is no room to run the std cover with the 2.25" coilover springs, so the seals got trashed. The KW's do have a built in cover but I wanted to be certain they'd stay clean.
KW's came from Danny at DNA

I did try seam welding the subframes, but even though they'd been cleaned there was still dirt trapped in the gap and I couldn't get it to weld cleanly with my TIG, if I'd have tried MIG it might of worked.sigpic
