Subframe Cracks: what else to get done?

[Heisenburg]

Mine was done as a preventative measure (no cracks found) by MProve near Warrington - plates, epoxy resin injection on both sides, new subframe bushings, etc. Would definitely recommend the guys there, and they've done a good few CSLs

Yeah...I may need to go down this route. Car has only done 33k, so not yet sure if it's cracked or not. BMW did mention the foam as a preventive measure briefly to me before...I take this will not be covered under their goodwill?

What sort of cost are we talking with MProve?

Mine had 54k at the time with no cracks, others with small mileage can. Talking to Matt there he reckons the damage is mainly done from hard 1st & 2nd gear manoeuvres

AFAIK, BMW will inject it afterwards, but only do one side, the weaker nearside. Suppose you could always ask them to do both, but I wanted the plates done too. I don't track my car so it's probably me just being paranoid!

Cost was £1200 as far as I rem

This was mine:


You need to drop the diff carrier to have a good look & remove the underseal (& shit).

The car should be covered by BMW if:

1) Its less than 10 years old
2) is not modified (this may depend on your dealer)
3) has covered less than 100k miles

no.3 is not really correct :whistle:

My car was fixed under warranty @ 107k this Febuary. Full BM history helps too.

Judging from the variance in the many stories I have heard, I think this is dealer dependant. When I got my standard M repaired last year, they just seemed interested in the age and if the car was (heavily) modified. Quite keen to look after me...for which I'm sure they are well compensated for.

J2LTB - did you have any other/ additional work done while the rear axle was off the car?

[J2LTB]

Yes my car had new RTAB and subframe bushes at my request. They charged me £400 for this additional work including parts.It was carried out at Knights BMW of north Staffs.

My car is a std Cecil with full BMW history. 107k at the time of repair. They said 2-3 weeks but it was close on 5 weeks in the end. With a Mini Cooper diesel to drive about in. Not to bad an experience really.

Yeah...the RTABs again. I will be looking out for these. Did they offer you a saving on the labour?

[northernjim]

Hello all,

Just wondering what other parts to consider replacing while the rear axel is off the car, and hopefully save on some labour.
.

Cheers

The rear brake lines can be worth replacing while everything is off :beer:



and welcome aboard :smokin:

Lol labour rates. They all make it up as they go along. Cheaper rate but longer times to make the difference up !

Kim is quite right about the rear brake lines. It's a job I'm kicking myself about now. As the pipes are drained and easy to remove . When the cars in that state.

Cheers mate

Yeah, heard this before. Are the OEM lines that rubbish? I have heard good things about what Goodridge offer...what sort of money are we talking to supply and fit?

Kim lol I meant Jim

We are taking about the actual lines not the hoses. But putting goodridge hoses on would hurt one bit.

Cheers fella...my bad. But same question with the lines...just trying to work out how economical this is? Do you know what sort of life you get out of the originals and what sort of cost to replace. This car has done 33k miles but has been driven as a CSL should. May be a worthwhile exercise.
