Faults on Grand Cherokee

Collected my WK Jeep Grand Cherokee today. The fault with the vehcile was crankshaft sensor compounded by new battery going faulty. I have been advised of the following faults by the Jeep specialist (not a dealership);

 

Cylinder 3 & 6 glow plug faults active ( whatever that means as engine seem to be running smoothly)

Front lower ball joints have excess play

Front inner steering arms have play

The nearside wheel bearing has play

Front axle support bush is seperated

Front anti roll bar links are seperated ( I am sure these were replaced about 2 years ago)

Front wishbone bushes are perished

All tyres are beginning to wear low (They are General Grabber HTS with about 28,000 miles)

The propshaft rear boot is split

 

I think some are rather suspect and probably made up as never heard fo glow plugs having active faults.  Obviously I will need to get all of the above repaired if genuine although the tyre replacement can wait a few months as still legal. If replacing glow plugs is it advisable to replace all six or is it okay just to repalce the two? Although all are essential I will need to get the most urgent ones done first. Can anyone advise the best order to have things done as not exactly flush with the ready cash. Thanks.

Start with the suspension faults / safety related items - ball joints and steering arms first, then the others can follow in order of urgency, however the rear propshaft boot should be relatively cheap to do and quite vital to protect the life of the joint which would be significantly dearer.

As for glow plugs, if it still starts well leave them be for now and consider changing before next winter.

That would be my priority list.

The glow plugs on the OM642 engine are always active their voltage is controlled by the GPM this helps with not only starting but emissions too

Update:-

 

Took the Jeep to the Inde and they had it to check over the so called faults found. They phoned me this afternoon and I was dreading the worse. They informed me that could not see anything abnormal with the vehicle. On collection the mechanic put the vehicle on the lift and then showed me the so claled faults. There were none! I have no mechnaical knowledge, but could see that bushes, anti roll links and wishbone bushes were okay. The front wheel bearing minimal play and he said it was not worth bothering about. The n/s/f ball joint had minimal play with the o/s/f slighly more but then again nothing to worry about. No issues with the prop shaft rear boot and it looked intact.

Unfortunately they did not have the equipment to check if there were any faults with the glow plugs without taking them out however he said it was simple job and not expensive. Again said that if vehicle is starting okay and running nothing to worry about however if I want they will change the glow plugs.

Is it worth having the just the two supposedly faulty glow plugs done or is it better to have all 6 done plus the control module or shouldn't I bother at all? Thanks.

Fools. You don't have to remove the glow plugs to check them. Just unplug them and check their resistance to ground.

An OBD II scanner would tell you without the need for removal or anything else .. codes P 0671 through to P0676 should tell you what glow plugs have gone code P0670 shows it;s the GPM itself that has failed

Stew the Jeep

If this is what you are posting elsewhere on another Jeep forum have the balls to speak to said garage and talk it through with with them they are good guys and discuss it with them, They work on my 3 Jeeps plus one I was loaned and I aint got no complaints

Stew Its hard to argue with someone when you havent the knowledge, if you feel you are been taken for a ride and get a second opinion which is more favourable then you have trust in your second opinion and will go there and build the rapport that you must have with the firat garags. Thats how it works.

It is possible the first garage didnt want the work, dont forget that, I'm glad you find them ok and thats good but you dont need to be telling other people what they should do.

I find your post a bit insulting.  I did query it initially when I collected the vehicle.  I then emailed Matt querying it and also asked for quotes as I beleived there was something seriously wrong with the vehicle.  It took Matt over a week to reply and only after I chased it on a few occasions as obviously the worry gave me a few sleepless nights.  Matt did not reply to my last email sent to them querying the prices again. 

As said previously we have had good service from them with no complaints however to come up with all these non existent "faults" is a bit off putting especially the rear prop shaft boot as there is no split in it!  The sway bar links and the front nearside bearing were replaced 18 months ago so not sure why they think they are faulty and certainly not falling apart.
