Re: Pulling to offside under braking

My point is a simple one - that a five second brake balance test is not going to do it any harm either.

Re: Pulling to offside under braking

Even if one side is completely inoperative, which is extremely unlikely, you're not going to wear out the clutch in a five second brake test. More to the point, if the front brakes are in balance, it suggests the fault is at the rear, so if you think the diff clutch is that delicate, you don't even ...

Re: Pulling to offside under braking

At least you'll know ;). Why should it damage the diff? It is, after all, a 'diff'. What happens when you go round a corner?

Re: Pulling to offside under braking

If the brakes are in balance it won't make any difference.

Re: Pulling to offside under braking

If it's giving you the run around, I would put it on a rolling road & do a brake balance test to make quite certain it's not the rears.

All that means is that your steering wheel is not centred. Where is it when you are driving?

Re: Pulling to offside under braking

Got to be the calipers. Modern hoses sometimes get blocked, but you've eliminated them. However, if one of the pistons were stiff enough to prevent the brake applying, it would also hold the brake on, and you'd know about that soon enough. But I would pull them off, measure all the bores & compare,,...

Re: Axle ratios

I still have the spare empty 2.88 Powr-Lok carrier (subject to confirmation) if you want to pm me. I didn’t see anyone mention the lack of a drain plug on Dana cases by which you can immediately tell a bare empty casing is Dana. They were used intermittently in the mid 80s on XJ and XJS. I still ha...

Re: Axle ratios

Ah - thank you; the way I read it (on an American site) was that the flange on the carrier was a different thickness to accommodate different thickness crown wheels. Now it makes sense - and I like it when things make sense. I had a brainwave late last night - what's to stop me machining 3/16" off t...

Re: Axle ratios

A lot of people do seem to want to go lower than 3.54 - not on E types obviously but on various track cars and off-roaders. Plenty of 4.xx's and even 5.36 gears out there. 2.88 gears are hard to find though. The after-market even supplies spacers so you can fit the thinner crown wheels to the thinne...

Re: Axle ratios

Starting to make sense - I just found this quote online; "2.88 & lower (2.69?) 3.07-3.54 3.77-4.10 & higher May be out a tooth here or there, but that’s the basic grouping. 3.54 can’t swap to 2.88 without other components swapped." So it seems there are three different carriers, not two as stated el...

Re: Axle ratios

Hugo, ...... A bit of a daft question, but is it possible for you to go back to the Ebay seller that you got the CW and P and ask where they came from and do they still have the diff carrier ? Regards, Dave No - I bought this ages ago & it's just been sitting on my shelf waiting till I plucked up t...

Re: Axle ratios

In an attempt tp get the Salisbury/Dana relationship quite clear in my head, I found this online. I know, "If it's on the internet it must be true". But this sounds plasuble; "Jaguar first used the Dana 44 in an IRS in 1961 for the Jaguar E-type as well as other models. It was used through 1996 (Jag...

Re: Axle ratios

Based on the fact that mine is a North American car, and that the entire rear end has already been rebuilt while in the States, I'm wondering whether somebody may have fitted a Dana gear carrier? As Dave 44DHR says, the 3.54 should use the same carrier as the 2.88 according to the info online (altho...

Re: Axle ratios

The plot thickens! Barratt's list three types of diff, each with and without 'powr-lock'. I think it is pretty clear that mine is the latest type (it's a 1970 car). What you say about the carrier makes perfect sense. But according to the online info for Dana axles (which is what I thought I was deal...

Re: Axle ratios

1) Yes I just bought the gears only as a matched pair. 2) The pinion cone height is marked as +.003. Trouble is there is a bit of confusion as to what the 'zero' measurement should be from the crown wheel centreline; my manual (on disc) says 2.625", but I have heard other say 2.635". But my manual a...

Re: Axle ratios

Thank you - but from what I can find, the housings are all the same (or the same size, anyway). There are variations in the shimming process for the crown wheel. Mine unfortunately entails pulling the bearings off to fit shims behind them on a trial and error basis. And even using a barbaric medieva...

Axle ratios

I had the bright idea of swapping the 3.54 diff on my 1970 US import OTS for a 2.88 CWP I picked up on ebay. Having spent ages carefully setting the pinion height, I find the crown wheel doesn't fit. In round figures it is a tenth of an inch thinner than the 3.54 crown wheel, while the pinion is hal...
